Full plate changes--plat19, plat22, plat23

[CamDawg]

Three sets of full plate have extraneous movement rate and THAC0 penalties. I've also included devSin's additional fix for plat22, which changes the displayed icon from resist fire/cold to protection from fire. plat22 and plat23 are both ToB items.
