Multiple root dir's recursion. Works fine, using them per repo needs to be figured out.
Figured out how use repository hash. Not fully implemented.
Renamed getRepository() in gitter Client, to avoid method name collision; some code cleanup.
Code for loading repo in TreeController.
Use checked-out branch as default branch.

Previously assumed 'master' was the default branch, when master may not

succeed, but it's certainly a step closer to correct.
