This setting originally only worked for the Summary page, but since that
page was written, other pages have offered graphing.  This setting will
now disable Google Chart requests on the Dashboard, Activity, and
Summary pages.

This is related to issue-310.

This is a work-in-progress and is mostly working like I want, but will require
some refactoring to make it even more useful and less complex.

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.
