Add the commons-io library explicitly to the depencencies.
It was already present as a transitive dependency but is now used in code.
Using the version 2.2 as that got so far already packaged in ext.

Add a new class, HtpasswdUserService, which performs authentication
against a text file created with the Apache 'htpasswd' program.

Added dependency on commons-codec:1.7

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.
