Weapons can now use Spearhead DLC magazines if its loaded

Most of the guns had same zero settings (100-600), now it depends on the weapon. For most Submachine guns it is now (100-200) and AB-46 and StG45 have 100 - 400
Initial zoom for the subguns (MP-3008, MP-41) was tad too low, as if character would position his head on the very end of the stock. Now it is much closer.
StG45(M) and Gustloff Volkssturmgewehr now have interchangeable magazines.
Switching any of the guns except the AB-46 and the shotguns to semi-auto was causeing the spread pattern to go absurdly wide. Fixed now.
