Purpose of change

@RoyalFox2140 pointed out that the glock 22 was spawning with the wrong ammo sometimes. The reason was that if the ammo group is not defined at the magazine when zero charges are possible, it may choose the wrong ammo type completely. This happened only for the glock 31 and glock 22 and every gun that uses their magazines.

Describe the solution

Define the ammo at the everyday spawn directly, same as the speedloader do.
Remove sig definitions for magazines that have no gun that uses that kind of ammo.
