[ros-users] Browse code links broken for git repos

The browse code link is wrong for git repos on the package detail page. For
example:

http://www.ros.org/browse/details.php?name=kinect_node, click on Browse
Code, and you get a link with a bunch of hudson stuff on it.
Other packages have the same problem, such as
http://www.ros.org/browse/details.php?name=cwru_nav or
http://www.ros.org/browse/details.php?name=kinect_camera.

Not sure how to link directly to a directory inside a git repo in all cases,
but it definitely shouldn't have a /hudson/workspace/<blah> on the end.
GitHub definitely has no idea how to find that path :).
