Changeset 1474 in eirsvn

Trololo update (because Vet5 is why), the AB crate (needs drop in ability and upgrade), and everything that the crate spawns. The LMG spawn ability needs to be finished (doesn't spawn the correct entity, and isn't dumped to lua). The spawn_allied_bar spawns thompsons (fyi). For some reason the mines ability I was working with didn't save or something silly; the same issue cropped up with the Extra Mags ability+items. Uhhhhh.. ah, I'll be in NY, NY for the next 4 days. Soz :'(
