Present the mutable permissions by default.  Allow the administrator or
owner to toggle the displayed permissions to see how the user
and team permissions are applied to a repository.

There are now three new targets on the ANT build:
- buildJAR: creates a GitBlit JAR including the GitBlit biz logic
- installMaven: install GitBlit JAR as Maven module
- uploadMaven: uploads GitBlit JAR to a Maven repository

Additional extensions have been made to allow:
a) GitBlit to load his resources outside of Wicket domain
b) GitBlit to use an injected UserService
c) Generic authentication of HTTP Request using 3rd party logic
d) Load settings programmatically from an InputStream
e) Use cookie authentication OR generic HTTP Request
   authentication for Wicket pages
f) UserModel with branch-level security logic

This is an in-progress feature to offer an interface for grouped
repositories.  This may help installations with large numbers of
repositories stay organized.  It also will be part of a future,
more advanced security model.

Reorganization of resources. Dropped most hard-coded webapp
configuration in favor of common web.xml file. Still contemplating
configuring git servlet from web.xml too.
