Instead of deleting the empty directory placeholders, let's just not copy them to pkg-temp to begin with.

getReleaseNumber and getBuildNumber were *NIX only targets that relied on the external tools grep, cut, awk, and tr. These targets have been rewritten to use ant features.

If someone runs "ant debian" to make installable packages, they do not need to
have their own wrapper or commons-logging  jars. The PPA builds, however, do
require them. During the last release I made the mistake of overwriting my "PPA
debian/control" file with the one from MTN that did not include these
dependencies.

Also updating "debianhowto" to reflect the fact that we no longer use
Debian's/Ubuntu's Jetty pkgs since Jetty6 appears to be leaving their repos in
the near future.

The directory installer/lib/ will be removed if a 'stripped' source tarball is
required. Without the changes in this commit, removing this directory will
require hackery to be performed on the I2P source in order for any of the ant
targets to work.

- Don't lose all DHT peers if we stop quickly
- Explore a kbucket if it's less than 3/4 full
- Change release torrent file names

- Remove unused UpdateTypes
- Only try applicable updaters when updating
- Javadoc fixes

- New Storage.main() for use in the release process
- Make torrent files in release process
- Stop tunnel after fatal if no snarks are running

  - Include jetty-i2p.jar in the updaters

.command extension make it possible to double click on it like bat files
in windows. Daemon is runned as the user who executes the command file.

I need to investigate a cross-platform method.

Izpack tries to parse the 'unix-only' files in Windows. If we don't copy them,
the installation will fail in Windows. Therefore, moving the files that were in
the preppkg-unix target to the preppkg-base target. They're so small I don't
see how this will be a problem.
