Making KDE and GNOME separate.
The difference from previous is:
Earlier guide: Used totem-browser-plugin and deps to give playback of some of the trickier stuff (apple movie trailers) and k3b was added because brasero is flaky.
**Now: **KDE uses gecko-mediaplayer to remove gnome packaging (though this does install gnome-mplayer). K3B has been removed from the Gnome code.
*NB: Do Not install gecko-mediaplayer in Gnome
