FOOK2 ammunition overhaul

AK47\'s now use 7. 62x39mm, MP5\'s now use 9mm,SVD\'s now use 7. 62x54mmR, FN five-seven\'s now use 5. 7mm. Every gun that has a real life counterpart now uses the same ammo as that real life counterpart, but I left alone fictional guns and nicknamed guns. I made reasonably sure that NPC\'s spawned with the right ammo and I added the new calibers to vendors, but NPC\'s that have already spawned might have the wrong ammo. New ammo chambers include: 4. 7x33mm Caseless 5. 7x28mm 7. 62x39mm 7. 62x25mm Tokarev 7. 62x54mmR 7. 92x57mm Mauser 7. 92x33mm Kurz 9x18mm Makarov 9x19mm Parabellum 9x39mm Subsonic . 30-06 . 338 Lapua Magnum . 357 Magnum . 50 BMG Some calibers only have 1 gun that uses them, while others like 5. 56mm and 9mm are ubiquitously used. Also I made guns that used . 308 use 7. 62x51mm as the . 308 cal. was redundant. Requires FOOK2 1. 0 RC
