Update process docs and Makefile for git releases.

- Update the makefile to convert bzr-ism to git-ism
- I have qa'd a developer release up through uploading, but killed it when I needed to auth launchpad with an oauth credential.
- I have followed most of the release steps, but not all. There might still be a snag/two to work out on our first real release which we'll do next week and I'll volunteer to help with that in case I've missed a step, I just don't want to go through with a real release right now.
