Migrated to Git and GitHub

[Scott Willson]

The core code repository is now on GitHub:
http://github.com/scottwillson/racing_on_rails/tree/master

The site-specific "local" repositories are still on butlerpress.com,
but are Git repositories now. No more Subversion.

Because Subversion + Trac on my server has worked fine, I've been
reluctant to switch to Git and GitHub. But the most active Racing on
Rails developers almost all use Git, and it does seem to make long-
term branching and merging easier.

I've done a production deploy with Git to ensure it works, the CI
build now uses Git, and Trac is (mostly) integrated with GitHub.

Hopefully, this will make it easier for others to help with the code.

This has gone very well, and fun to see the commit history live on
GitHub! Scott definitely has the cutest gravatar, but mine is from an
actual bike race. I will try to make it appear more.

Thanks for the hard work, Scott. I upgraded my git version to
1.6.2.5, I was so excited. This moved a bunch of git-* commands out
of bin and into libexec, which is cleaner for me.

I recommend the git shell. http://github.com/rtomayko/git-sh/tree/master
