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.

x11: remove 'Created by' lines

Upgrade the Cinnamon desktop environment to version 4.8

This version uses Python 3 instead of the expired Python 2.7

From the main PR (249856):

" There are a couple known issues:
  * x11-fm/nemo crashes upon closing a window or tab.
  * x11/cinnamon-screensaver unlocking doesn't work, most likely due to a
missing PAM (Linux-PAM?) integration.
  Both of these issues are being worked on.

  I've been dogfooding since Cinnamon 4.0, and apart from those issues,
everything works."

The FreeBSD GNOME team proudly presents GNOME 3.14 and Cinnamon 2.2.
Gnome 3.14.1 and Cinnamon 2.2.16 are supported on FreeBSD 9.3-RELEASE and up.

This commit removes the old GNOME 2 desktop, bindings and some ports that
can't be compiled. A few ports where updated to more recent versions to
allow them to compile with this update.

Apart from updating ports to newer versions

GDM is more integrated with gnome-shell now, and handles several things for
the GNOME desktop such as screen locking. If you want to use GNOME 3 via
startx, you will have to add your own lock screen/screensaver. For example
xscreensaver
can be used for sessions started without GDM.

Shell Extensions can be installed via https://extensions.gnome.org/ , we have
