Allow browsing branches that end with '.atom'
We need to do two things to support this: 1. Simplify the regex capture in the routing for the CommitsController to not exclude the '.atom' suffix. That's a perfectly valid git branch name, so we shouldn't blow up if we get it. 2. Because Rails now can't automatically detect the request format, add some code to do so in `ExtractPath` when there is no path. This means that, given branches 'foo' and 'foo.atom', the Atom feed for the former is unroutable. To fix this: don't do that! Give the branches different names!
