Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories x

Add USES=xorg and USES=gl to ports in categories starting with 'x'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Update MASTER_SITES and WWW

Change x11/xorgproto to become a build dep

Change x11/xorgproto to become a build time dependency when added to
USE_XORG.  Change the dependency to be on the port, rather than a file the
port installs.
Fix fallout.
Bump portrevision on depending ports.

Switch to xorgproto instead of individual packages

Upstream used to distribute protocol headers as separate packages, but has
decided to merge those to a common package, named xorgproto.  This update
tracks that change.

* Add a new port, x11/xorgproto, with are protocol headers for xorg.
* Hook the new protocol port to the build and to infrastructure in
  bsd.xorg.mk.
* Update all ports with a dependency on any of the old *proto packages to
  instead depend on xorgproto.  Bump portrevision.
* Delete the old *proto packages, update MOVED.
