Add a way to undo polymorph

[NateTheSquid]

I have spawned beardless many times as a wizard, so unless they fix that shaving isn't an option. I think that it should still decurse victims if the wizard dies even discounting soulgaurd, as having it persist would be a soft-detection method for soulgaurd. "The captain is still a space pug, the wizard must have soulgaurd."

the crew will notice in the next 30 seconds when the wiz tries to teleport into the room they are in and kill them. no wiz tries to be sneaky at any point in time
