connectors, so Jetty will still start without them

      to eliminate races with ReadConfigJob

    - Fix failsafe shutdown hook broken in 0.8.8;
      HUP, INT, and TERM signals should now shut down cleanly.
    - Shutdown hook no longer prevents other hooks from running
    - Trap HUP, if router.gracefulHUP=true, and do graceful shutdown.
      Only under wrapper, non-Windows.
    - i2prouter stop now uses SIGTERM
    - Implement i2prouter graceful using SIGHUP (ticket #580)
    - Configure wrapper to ignore SIGUSR1 and SIGUSR2 as they will shut down
      or crash the JVM

- Add delay in systray port checker to ensure console is up
- Move I2PRequestLog to net.i2p.jetty package

- Uncomment eepsite concurrent ThreadPool and fix arguments
- Reduce eepsite acceptors to 1
- Add jetty-ssl.xml example
- jetty.xml cleanup

- Fix nowebapp.jsp for non-started webapps
- Fix nowebapp.jsp for url /foo for non-started webapp foo

Jetty 6 package.

- Add several jars from the Jetty 6 distribution
- Update jetty.xml
- Add context XML files
- Update WorkingDir to migrate the content XML files
- Update RouterConsoleRunner and LocaleWebAppHandler
- Remove all old Jetty 5.1.15 local mods;
  this will break Seedless using a custom Server() constructor
- Update I2PRequestLog to be a mod of NCSARequestLog from 6.1.26
- Put I2PRequestLog in its own jar
- Copy MultiPartRequest and other required classes from Jetty 5.1.15
  and add it to susimail, as the replacement MultiPartFilter in
  Jetty 6 is difficult to migrate to, and does not support content-type
- Update i2psnark for Jetty 6
- Disable i2psnark RunStandalone, unused and instantiated Jetty 5
- Fix up all webapp build.xml to reference new jars

Not yet working: Plugin/webapp run detection and stopping, eepsite CGI
Not well tested: Plugins, classpaths, webapps

Add hooks so the new PortMapper lets i2p plugins not fail when the router console is not on port 7657. Also raise an exception when requesting unregistered ports so as to encourage swift adding of the registration hooks when those ports are taken.

    - More refactoring tasks to their own files
    - Adjust some thread priorities

    - Implement and call shutdown for BandwidthRefiller
    - Implement and register shutdown hook for Timestamper
    - Implement and register shutdown hook for Jetty console server
    - Fix UPnP-SSDPNotifySocket thread not stopping
    - Fix all but one UDP PacketHandler threads not stopping

      - Fix numerous readme HTML errors
      - Fix flag locations in readmes
      - desktopgui.enable now defaults to false; run systray if false
      - Start icon app before console
      - Restore systray form in configservice.jsp
      - Only save lang when clicking on flags if desktopgui is running
      - Only allow two-letter lang code from cgi parameter

- Added correct 'stop I2P' functionality in desktopgui.

               set min/max threads and idle timeout

      - Add SSL support - To enable, change clients.config. Examples:
            ## Change to SSL only - just add a '-s'
            clientApp.0.args=-s 7657 ::1,127.0.0.1 ./webapps/
            ## Use both non-SSL and SSL - add '-s port interface'
            clientApp.0.args=7657 ::1,127.0.0.1 -s 7667 ::1,127.0.0.1 ./webapps/
            ## ...and change URLLauncher args further down for the browser to open https:// at startup if you like.

      - Always show start button for webapps and plugins
    * configclients.jsp, configupdate.jsp:
      - Fix submission when entering CR in a text box
    * Plugins:
      - Stop all plugins at shutdown
      - Log tweaks
    * WebApps:
      - Remove the WAC after stopping it
      - Stop a WAC before starting it to prevent dups

      - Hook up update/delete/check/save buttons
      - Implement delete
      - Hide unless router.enablePlugins=true

      - Pull jstl.jar and standard.jar out of susidns.war
      - Remove 100KB of duplicate classes from i2psnark.war
      - Add classpaths for plugins

      - Persistent lang setting with routerconsole.lang=xx
      - Loading any page with ?lang=xx changes the persistent setting
      - Add a custom Jetty handler to load foo_xx.jsp if it
        exists for language xx. This is for jsp files with lots
        of text in them. Otherwise use inline translate methods.
        Not for included jsps.
      - Add a script to create and update messages_xx.po translation
        files, and create ResourceBundles from them
      - Add class to translate strings from cached ResourceBundles
      - Add translate wrappers to HelperBase, FormHandler, and *Renderer,
        so calls can be made from both jsp and java files
      - Add two example translations on configupdate.jsp - one in
        the jsp itself and one in the helper.
      - This is for strings in routerconsole only. Will be expanded
        to other webapps and the router later.

      killing the router

    * Router: Don't do some things when we are shutting down
    * VMCommSystem fixups

      - Move reseeding from the routerconsole app to
        the router, so that we can bootstrap an embedded router lacking a routerconsole
        (iMule or android for example), without additional modifications.
        This allows better integration between the reseeding function
        and the netDb.
      - Call reseed from PersistentDataStore, not from the
        routerconsole init, and start seeding as soon as the netdb has read
        the netDb/ directory, not when the console starts.
      - Wake up the netdb reader as soon as reseeding is done,
        rather than waiting up to 60s.
      - Don't display the reseed button on the console until the
        netdb initialization is done.
    * NetDb:
      - Fix an NPE on early shutdown
    * RouterConsoleRunner:
      - Catch a class not found error better

      - Fix webapps file path
    * SusiDNS:
      - Fix addressbook file path
    * Systray:
      - Fix NPE if no config file
      - Fix config file path
    * WorkingDir:
      - Modify clients.config so jetty can find the jetty.xml file
      - Rip out all the existing-installation migration code
      - Rip out migration code now done by izpack parsable
      - Fix copy of empty directories

Eliminate all uses of the current working directory, and
set up multiple directories specified by absolute paths for various uses.

Add a WorkingDir class to create a user config directory and
migrate files to it for new installs.
The directory will be $HOME/.i2p on linux and %APPDIR%\I2P on Windows,
or as specified in the system property -Di2p.dir.config=/path/to/i2pdir
All files except for the base install and temp files will be
in the config directory by default.
Temp files will be in a i2p-xxxxx subdirectory of the system temp directory
specified by the system property java.io.tmpdir.

Convert all file opens in the code to be relative to a specific directory,
as specified in the context. Code and applications should never open
files relative to the current working directory (e.g. new File("foo")).
All files should be accessed in the appropriate context directory,
e.g. new File(_context.getAppDir(), "foo").

The router.config file location may be specified as a system property on the
java command line with -Drouter.configLocation=/path/to/router.config
All directories may be specified as properties in the router.config file.

The migration will copy all files from an existing installation,
except i2psnark/, with the system property -Di2p.dir.migrate=true.
Otherwise it will just set up a new directory with a minimal configuration.

The migration will also create a modified wrapper.config and (on linux only)
a modified i2prouter script, and place them in the config directory.

There are no changes to the installer or the default i2prouter, i2prouter.bat,
i2prouter, wrapper.config, runplain.sh, windows service installer/uninstaller,
etc. in this checkin.


    *  Directories. These are all set at instantiation and will not be changed by
    *  subsequent property changes.
    *  All properties, if set, should be absolute paths.
    *
    *  Name	Property 	Method		Files
    *  -----	-------- 	-----		-----
    *  Base	i2p.dir.base	getBaseDir()	lib/, webapps/, docs/, geoip/, licenses/, ...
    *  Temp	i2p.dir.temp	getTempDir()	Temporary files
    *  Config	i2p.dir.config	getConfigDir()	*.config, hosts.txt, addressbook/, ...
    *
    *  (the following all default to the same as Config)
    *
    *  Router	i2p.dir.router	getRouterDir()	netDb/, peerProfiles/, router.*, keyBackup/, ...
    *  Log	i2p.dir.log	getLogDir()	wrapper.log*, logs/
    *  PID	i2p.dir.pid	getPIDDir()	wrapper *.pid files, router.ping
    *  App	i2p.dir.app	getAppDir()	eepsite/, ...
    *
    *  Note that we can't control where the wrapper actually puts its files.

All these will be set appropriately in a Router Context.
In an I2P App Context, all except Temp will be the current working directory.

Lightly tested so far, needs much more testing.
