Fixed damaged overlay.
Damage masks for chest and groin were named wrong.
Fix: Engineering borg's 'Antique' sprite being invisible. Blasted caps.

New: Rowtree's 'Lucy' Cyborg and Serithi's 'REMNANT' AI Core sprites implemented.

Tweak: Cult's conversion rune failure text tweaked so something a little more immersive.
Eep, this is needed for Serithi's custom sprite, forgot one last ctrl-s

No fun allowed.
