x11-wm/wm{2,x}: add LICENSE (MIT) to Chris Cannam's window managers

Original sources did not include explicit license information, just
mentioned that a lot of code and structure were borrowed from David
Hogan's 9wm which AFAICT is MIT licensed.

Chris had confirmed with me via email that the MIT licence reflects
the general assumptions of the time and have added COPYING files to
the corresponding repositories:

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.

Approved by:		portmgr (tcberner)

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.

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.

Resurrect `x11-wm/wmx' port removed by kris@ on Feb 18, 2005.  It is still
well alive, with the latest version released last year.  Submitter assumes
maintainership.

PR:	199977 (modified)

As previously announced, remove ports that have reached their expiry date,
and the handful of ports that depended on them.

This port is scheduled to be removed on 2005-02-18 if it is still
broken at that time, and a fix has not been submitted to GNATS.

Use IGNORE instead of BROKEN.

Layout fixes in x11-wm.    

Convert category x11-wm to new layout.  

(1) Add new variable, XFREE86_VERSION, to specify which version of       XFree86
(3 or 4) to depend to when USE_XLIB is set.       XFREE86_VERSION defaults to 3
for now, but adventurous users can       override it in /etc/make.conf.  When
XFREE86_VERSION=3, USE_XLIB       will add a dependency to x11/XFree86; when it
is set to 4, the       dependency will be to x11/XFree86-4-libraries.  When     
 XFREE86_VERSION=4, the PKG_IGNORE_DEPENDS and ALWAYS_BUILD_DEPENDS       hacks
to avoid messing with XFree86 are turned off.
