Settings overhaul. Fixes to authentication. Bind interface feature.
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.
Authenticate the webapp against the same realm as the git servlet.
Right now the implementation is hard-coded to pass the realm into a
singleton. This won't work for a WAR distribution so I will
need to figure out how to properly authenticate the webapp using form
authentication and the git servlet using basic authentication - host
against the same realm.
