first shot at moving build tools into the git framework.

first shot at moving build tools into the git framework.

I intend to make these consistent across horde and horde-hatchery, so that
people don't need to pull CVS just to symlink a framework setup. Naming and
organizational suggestions are welcome. This also renames a few scripts, makes
lib/ the default (instead of libs/) for H4, and standardizes the test runner as
a script instead of a weird psuedo-class.
