The graph is generated server-side and therefore requires that the
commit table row height be fixed and match the row height of the
servlet.  There will be layout misalignment if remotes refs are
displayed.  Perhaps this can be improved in the future.

* Properly support timezone-based date groupings
* Polish css for the major browsers on Win & Linux
* Use Gitblit constants for refs instead of JGit constants

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.

This reverts commit 5ad03d053f.

* 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.

This seems to improve page loading times.
