Cargo fixes
Bunch of stuff. Beautifies the S-COM headquarters, deletes one of the heavy's closets and replaces it with sniper. Adds a sniper to the game. Fixes the plasma pistol. Adds an alternate uniform (or two) for the detective, one of which you can roll up the sleeves on, for those special interrogations. Makes a better alt RD sprite, expands the naval shuttle a bit, fixes some minor map stuff, adds more carp spawns and adds lattices near the new toxins testing range.
