audio/opus: bump consumers after update to 1.4

*: Bump PORTREVISIONs for math/mpc update to 1.3.1

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.

gnome: remove more reference to gnome 3

gnome: gconf-editor is not part of gnome anymore

gnome: replace vinagre with gnome-connections

vinagre has been deprecated along with gnome3 and replaced by
gnome-connections

x11/gnome: Update to 42

The majority of the GNOME-related packages are at version 42, so we
should bump the x11/gnome meta port as well.

GNOME: Don't depend on graphics/gnome-color-manager since its outdated and
broken

x11/gnome: fix dependency on x11-themes/gnome-backgrounds

- the file used in the dependency line was dropped in the most recent
  update to x11-themes/gnome-backgrounds

x11/gnome: Move from x11/gnome3

The reason for the move is because GNOME has moved beyond version 3,
bumping directly to 40 and iterating major release versions from there.
The Ports version of GNOME is currently at 41, making x11/gnome3
misnamed also.

Differential Revision:	https://reviews.freebsd.org/D33959

Begin the de-orbit burn of the GNOME 1.4 desktop.  This is phase I.  All
core desktop components are being removed.

Clear moonlight beckons.
Requiem mors pacem pkg-comment,
And be calm ports tree.

E Nomini Patri, E Fili, E Spiritu Sancti.

Directory layouts of py-gtk and py-gnome packages have been changed, so that
update *_DEPENDS properly.

Don't use old USE_GNOME framework, as it is now being actively deorbited.

Add a WWW entry that points to the FreeBSD GNOME project site.  This way,
new GNOME users will know where the FreeBSD-specific docs and FAQs are.  The
FreeBSD GNOME site can then redirect them to gnome.org for additional
information.

Use xscreensaver-gnome instead of xscreensaver    

Pull the trigger - make Nautilus a default filemanager for a GNOME desktop  
instead of good old gnomemc. This should give more testing to it, and let   us
ship 4.5 with Nautilus installed by default.    

Sync PORTVERSION with gnome-fifth-toe.    

Bump PORTREVISION of the metaport to indicate the structural changes below.    

Add pkgconfig support to most of the core of GNOME 1.4 and GTK+/GLIB 1.2   to
make transitioning to GNOME/GTK+/GLIB a little easier.    

Split gdk-pixbuf into the non-GNOME part (gdk-pixbuf) and the   GNOME part
(gnomecanvas) to allow for other ports to access   the lower level parts of
gdk-pixbuf without the "excess baggage"   of even a minimal GNOME environment.  
 

SWitch maintainership of core GNOME ports to a small group of   committers
(gnome@FreeBSD.org), since this is now definitely too big   for just one person.
   

Update to GNOME 1.4 -- massive changes all around, for the sake of   CVS repo
bloat, I'll only list the updates.    

It's high time that the GNOME metaport got cleaned up to actually   USE_GNOME :)
   

Chase new print/gnomeprint shlib version    

Fix breakage cause by the destruction of python-1.6    

Convert category x11 to new layout.  

Chase new gnomeprint    

Depend on right file for py-gnome (version change).    

Update for new devel/libglade shlib version    

Fix typo.    

Explicitly mention a few more dependencies.
