Try server and buildbot scripts now using Chromium scripts.

- 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.
