2014/03/15 Quick Fix

Aside from being an idiot when tired, I DID manage to notice my first
draft was trying to look for "a9mmDU" when firing.

... a9mmDU is unloaded ammo. It's alternate is called LoadedGLK_DU for a
reason. SO NOW THE GLOCK FIRES ALT AMMO! Woo.

NEEDED IMPROVEMENTS
• ACS update to AmmoSwap
• HudInfo needs new display stuff for LoadedGLK_DU and a9mmDU
