Weapon entities do not spawn as physics objects or replenish ammo

[DESTROYGIRL]

When trying to add a weapon entity to a map, they can be picked up and used, however they have no physics and will stand upright and motionless. This isn't the case in OGNT
Edit: They don't replenish ammo either as they should.

same with weapons created with the ent_create command

The replenishing ammo half of this issue might be its own thing entirely or got mixed up with something else so marking this as fixed by #1195
