Caustic shotgun rounds. (sojourn-13#4723)

* Caustic shotgun rounds.

Credits to @uzkulari_ur for concept, writing and sprites.

New caustic shotgun rounds for the Church, obtainable primarily via the EOTP, but also available in the regulator design disks.

High AP, High Pain, low damage - great for mobs, solid for when you need AP and LTL capacity for some reason.

* Fixes some commenting and moves the disk around
