This is a massive commit which reorganizes the entire project structure
(although it is still monolithic), removes the Build classes, and
switches to Moxie, a smarter Ant build tookit based on the original
Gitblit Build classes.

The Ant build script will likely require additional fine-tuning, but
this is big step forward.

* Clarified SSL certificate generation and configuration in light of the
hostname verificiation that JGit currently does despite
the http.sslVerify=false setting.

* Added some troubleshooting information related to filesystem
permissions and reading repositories.

* Switched from JavaService to Apache Commons Daemon.  Not sure what
happened to JavaService as it stopped working for me on Windows 7 with
Java 1.6.0_26.  Commons Daemon accomplishes the same thing and offers a
nice service control utility.

* Build script overhaul including building & publishing GO, WAR, Docs,
and Site.
* Restored JGit 0.12.1 dependency and backported Blame.  Got tired of
waiting for JGit 1.0.0 Maven artifacts.
* Changed Summary Page layout
* Optional cookie authentication
* Added icons for log, tags, and branches panels.
* Show last commit author and short message on branches panel.
* Unit testing.
* Documentation.

Reorganization of resources. Dropped most hard-coded webapp
configuration in favor of common web.xml file. Still contemplating
configuring git servlet from web.xml too.
