versioncontrol 6.x-1.0-beta3

Fixing more trivial errors. Oh my. At least there should be no syntax errors in any file now, which means the actual testing can begin. I'd like to test stuff out more by myself, but I need to get other stuff done before I can get back to Version Control API. Also, the link to the non-functional beta1 release notes which explain what you can expect from this 6.x-1.x series in the first place.
