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.

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.

The fork mechanism clones the repository , access restrictions, and
other config options.  The app has been updated throughout to handle
personal repositories and to properly display origin/fork links.

In order to fork a repository the user account must have the #fork role,
the origin repository must permit forking, and the user account must
have standard clone permissions to the repository.

Because forking introduces a new user role no existing user accounts can
automatically begin forking a repository.  This is both a pro and a con.

Since the fork has the same access restrictions as the origin repository,
those who can access the origin may also access the fork.  This is intentional
to facilitate integration-manager workflow.  The fork owner does have the
power to completely change the access restrictions of his/her fork.

TimeUtils needs to output localized strings like "5 days ago" and "6 months".  In order to do this it needs a translation resource.  Additionally, that resource can not be static because the single Gitblit server can handle multiple connections in different locales/languages.

TimeUtils has changed from a collection of static methods to some static methods and some instance methods.  A TimeUtils is instantiated with an optional resource bundle which contains the preferred translation.  If the resourec bundle is null or the requested translation key does not exist, an English  default will be used.

This change required adjusting the signatures of several key methods and that cascaded out to adjusting those methods calls in many, many  classes.

Settings access has been abstracted and the way is becoming clear to
offer a WAR build in addition to the integrated server stack.  Util
methods moved around.
