[aur-general] Exchanging glest with megaglest

[Sven-Hendrik Haase]

 Development on glest has been halted and due to that the megaglest fork
has been started. I'd like to drop glest to AUR and move megaglest to
community in its place. I feel this is the right thing to do since any
player would want the more featureful and actively developed version.

If nobody is going to hate me for it, I'm going to move it in 1-2 days.
