Title: Removing valiations on git-url --> they are too restrictive

Some people have been using the git url field for entering an svn link. Also, some people are using a tag, instead of a commit id in their git-url.

In both cases, the validations will not like those inputs. Thus I decided to remove those validations to help in those cases.
