In xscreensaver 5.07 the xml files for optional screen savers have been
removed. In order to continue supporting those screen savers that we have
in the ports tree I'm adding enhanced versions of the 5.06 xml files to
the port. The xml file installed by this port is "bare bones," while the
one from xscreensaver 5.06 has more features, so remove the option to
intall the one from this port.
While I'm here, man pages are not PORTDOCS.
I'm making this change on a short maintainer timeout (6 days) because
the xscreensaver 5.07 update is blocking on this, and I haven't heard
anything from the maintainer of this port.
