Updated ZMarket to distribute grenades correctly. Still need to update the loadout to support multiple nades, to support multiple flashbangs and Grenade Pack fully. As of now the market allows you to buy 3 grenades but they don't show in the loadout as 3.

Worked more on the voice API, need to figure out why they are reversed. The cvar to disable it now should work, because it doesn't quite work right.
Changed Gangsta Glock back to Glock :P
