Added a new category for MP Mods.Someone mentioned that GCM is not listed here. It's more than just a mod, but part of it is just a mod.

The "mod" part includes:
Random maps and hundreds of map variants, plus fixes for the default maps
Comprehensive gameplay mod
Scenarios (accessed via various scenario generators)
Tweaked versions of RebBugler's toolbar and the stock toolbar
Jolly's terrain mod
My map icons mod
Not sure how you'd categorize it.
