This patch allows loggerhead to serve Bazaar branches over HTTP. It
does this by catching requests to any paths with a '.bzr' segment, and
ensuring that those paths are served with a static application, rather
than with the branch application.

I've added a box with information about how to get the branch to every
page in loggerhead. It's not beautiful, but it's a start. To do this
well, I've had to tweak the CSS a bit. Hope it's OK.
