* The project moved to Gitlab and the old site has vanished.
* Update the distinfo accordingly, the new tarball is cleaner and doesn't
contain patch backup files, generated config.h headers, etc. Apart from
that there are no differences regarding the source code.
* Also add "gnome" to USES while I'm here as using USE_GNOME alone is
deprecated.
