Slightly reordered the MASTER_SITES, since gatekeeper doesn't seem to
be up-to-date yet.
The port still doesn't compile out of the box, since the standard make
sequence for our ports doesn't invoke `xmkmf -a', but xlockmore does
need it.
Most of the old patches are no longer needed. The app-defaults
have been slightly modfied (so `image' is the default mode
again, giving us the daemon image).
