MBF21: Weapons don't consume ammo

[Marisa the Magician]

First noticed in Ad Mortem. With the exception of the Super Shotgun, all other new weapons in the wad don't appear to consume ammo when fired.

Edit: It appears this issue also affects the weapons in Vesper (same thing: pistol, shotgun, and chaingun replacements don't consume ammo either), so it may be a generalized issue.

Should be fixed now - that ammo checking logic is an utter mess, and MBF21 only made it worse.
