Add repo start support for GITC checkouts. If the user is in the GITC FS view, they can now run repo start to check out the sources and create a new working branch. When "repo start" is called on a GITC project, the revision tag is set to an empty string and saved in a new tag: old-revision. This tells the GITC filesystem to display the local copy of the sources when being viewed. The local copy is created by pulling the project sources and the new branch is created based off the original project revision. Updated main.py to setup each command's gitc_manifest when appropriate. Updated repo sync's logic to sync opened projects and updating the GITC manifest file for the rest. Change-Id: I7e4809d1c4fc43c69b26f2f1bebe45aab0cae628
