Contract graphics/cal3d-devel into graphics/cal3d

The development of cal3d stopped in July 2006, about a week or two
after the last release (0.11.0). It makes no sense to have both cal3d
and cal3d-devel, so let's copy over the -devel port over to the stable
one and remove the -devel port. There's no reason to set a deprecation
period in this case.

While here:

• remove conflicts
• Update the WWW to the new home page

I've given graphics/cal3d a "fake" version of 0.11.1 to convey that it
is an update to the previous version of 0.11.0 rather than to completely
change the version scheme.
