Add a way to undo polymorph

[Vitatroll]

It'd be either a spell/prayer/ability or whacking them over the head with a bible like with cluwnes, if that were the case.

I'd rather polymorph not become something easy to fix. I think it's great fun to go flapping, cooing, gobbling, etc - around the station. Don't need to stinkin' chaplain 'curing' me with one thump on the head. Not to mention it'd make polymorph fairly pointless offensively.
