Focusing on MATE.

When I started this project at the time Nahuel joined me, GhostBSD was about having the best Gnome desktop experience, today having a bunch of desktop that do not work correctly with BSD. Gnome 3 had not seen ports yet, because it is basically made for GNU/Linux. I had make a critical decision lately with the rest of the team to abandon all the other desktops in favor of MATE, which is the most suitable solution for GhostBSD a workstation. The MATE Desktop Environment is the continuation of GNOME 2 desktop Environment with huge improvement.
