clonable repository url in hook response.
Created by: remcoros
The repository url in the response of the webhook doesn't point to a clonable url. It points to the web interface.
In the case of github, you can http clone from such an url (without the .git postfix). Tough gitlabhq http url's must end with '.git'.
I need in the response the url where I can pull from.
I can add '.git' to the url on the client side, but that feels kind of dirty.
I think gitlabhq should add '.git' to the url OR add a new property (like 'clone_url' or ssh/http_clone_url) with the correct url.
