- compatible with depot_tools try commands. - old build master is converted to use Chromium scripts, according to http://www.chromium.org/developers/testing/chromium-build-infrastructure/getting-the-buildbot-source/forking-your-buildbot - slaves can now be run out of a plain checkout, no local configuration needed. Also added files to make it possible to use tools as a separate checkout. BUG=None TEST=Runs on local machine with remote slaves. I've successfully submitted try jobs with both git try and gcl try commands.

deleted (we can't look at timestamps there since the act of deleting a file
