Switch upstream for blackbox70, and upgrade to version 0.72.

The old upstream last had a release in November 2005, and the new
upstream in May this year.  In recent rebuilds, the old version
has developed "focus issues" when run with "sloppy focus", as is
my preference. The new upstream is a fork of blackbox but where
this among other issues have been fixed.

The patches have also been re-done and partly renamed, and some of
the old patches to build with SunPro have not been carried forward,
as I don't have a suitable system to verify that these are still
required.
