Subject: [PATCH] Enable git for any module where the "repository" option is
 set.  kdesvn-build will not correctly handle the "branch" option yet, but if
 you don't mind HEAD then you'll get the correct build for a KDE module.

For example, this works:

module amarok
  repository git://gitorious.org/amarok/amarok.git
end module

If you already have a subversion checkout in that directory, you need to remove it
yourself first, kdesvn-build won't delete your source for you.

Also, warn if you change the repository option since kdesvn-build also doesn't handle
that.
