I've added custom maps to the sniper server and removed some of the default maps.  Some of them are remakes of old UT99 maps.  Here is the map list:

DM-Bedroom
DM-CampGrounds]i[
DM-Casablanca
DM-DarkPsychoCity
DM-Deck-FPS
DM-Devolve
DM-Gateway
DM-GOD-Backyard
DM-Lost-Tombs-Of-Ramen-Noodle
DM-PsychoBathroomHeaven
DM-Sanctuary
DM-Sentinel
DM-ShangriLa
DM-Tiberium-SE
DM-WoodShop

If people end up playing on this server I may update some of the mutators as they are unfinished (last updated before patch 1.1 was released).
