Make all weapons available of the wall :D

There's only 39 confirmed weapons (minus the Ballistic Knife and Crossbow, which just wouldn't work in Zombies), and chances are some of the weapons *glances at pistols* would be redundant to add, and others just wouldn't be added for some reason (Type 99 and DP-28, anyone?). If it's a large enough map, its' certainly possible.
