Prevent looting of dead bodies

Temporary fix for the duplicating of weapons on bodies.
This will prevent anyone from looting a dead body, and in the end this
should encourage less shoot-on-sight situations.
Revival/Respawn tweaks

Hoping that by updating the Hud in fn_revived it should update the
Textures properly. Otherwise it wont do anything and wont harm any of
the code. It also looks nicer this way ad makes more sense.
