implementing out-of-console updaters like i2psnark.

- Add new update interfaces in net.i2p.update
- All update implementations moved to routerconsole update/
- Implement an UpdateManager that registers with the RouterContext
- UpdateManager handles multiple types of things to update
  (router, plugins, news, ...) and methods of updating (HTTP, ...)
- UpdateManager maintains list of installed, downloaded, and available versions of everything
- Define Updaters that can check for a new version and/or download an item
- Individual Updaters register with the UpdateManager obtained from
  I2PAppContext, identifying the type of update item and
  update method they can handle.
- Updaters need only core libs, no router.jar or routerconsole access required.
- All checks and updates are initiated via the UpdateManager.
- All status on checks and updates in-progress or completed are
  obtained from the UpdateManager. No more use of System properties
  to broadcast update state.
- All update and checker tasks are intantiated on demand and threaded;
  no more static references left over.
- Split out the Runners and Checkers from the Handlers and make the inheritance more sane.
- No more permanent NewsFetcher thread; run on the SimpleScheduler queue
  and thread a checker task only to fetch the news.
- No more static NewsFetcher instance in routerconsole.
  All helper methods that are still required are moved to NewsHelper.

The UpdateManager implements the policy for when to check and download.
All requests go through the UpdateManager.

For each update type, there's several parts:
    - The xxxUpdateHandler implements the Updater
    - The xxxUpdateChecker implements the UpdateTask for checking
    - The xxxUpdateRunner implements the UpdateTask for downloading

New and moved classes:

PluginUpdateChecker 		-> PluginUpdateHandler.java
PluginUpdateHandler.java	-> PluginUpdateRunner

new				UnsignedUpdateHandler.java
UnsignedUpdateHandler		->  UnsignedUpdateRunner.java
new				UnsignedUpdateChecker from NewsFetcher

UpdateHandler.java remains
new				UpdateHandler.java
new				UpdateRunner.java from UpdateHandler

move				NewsHandler from NewsFetcher
new				NewsFetcher
new				NewsTimerTask

new				DummyHandler


Initial checkin. Unfinished, untested, unpolished.

This was interfering with the plugins section, where HTML is intentionally
passed into the description field. Now, only when the description field is
being plugged into the value property of an input tag will it be escaped.
