links to revisions working. better resultstatus handling.

this does fix the status-colors to be less painful.  But wait!  There's more!

* links to revisions in the repository
* consolidated handling of result statuses
* ``$rootScope`` object of ``repo`` is now ``repoName`` 
* ``$rootScope.repo`` is now a full ``repo`` object as return from the ``repository`` endpoint.  This gives us access to things like the repo url, etc.  Sorry for the name change.

NOW how much would you pay?!?
