* These aren't supposed to be here!!
* Adds new Security pistol and large capacity magazines
* Removes new pistol from Security spawns
* Removed references of Beretta because it's not one
* Adds defines for world.tick_usage
* This provides no useful benefit whatsoever, but /tg and Baystation12 have done it, so it will make porting future code easier if we do too. No real harm done either.
