- fixed ammo usage issues with Dehacked modified weapons that switch attack code pointers. Unless Dehacked specifies an 'ammo use' value for a weapon any Dehacked modified weapon determines ammo use by attack function, like Doom did originally, and not by the weapon's AmmoUse property. This also addresses that the Cells/BFG shot value always modified the BFG itself.

- fixed: A_Saw depleted ammo after the attack so it still went through with it, even though it was out of ammo.
