Entity Weaponbox gives ammo for throwables but not the weapons themselves

[StroggVorbis]

The game removes hand grenades, satchels, tripmines and snarks from your inventory if you run out of them. While some of the weaponboxes found in Xen do contain ammo for these weapons, if you don't have at least one unit of ammo before picking them up, you will be unable to use any of the above weapons as you don't possess them any longer.

This would be nice to have fixed. Happens quite often in xen
