Add a way to undo polymorph

[Noah Buttes]

90% of the time, you end up as something with no hands or ear slots, so unless you were in the hallways, you're unable to leave the room you were in cause you have no ID, can't contact anyone to let you out, and don't even have hands to interact with anything that might be able to let you out, so all you can do is animal around for a few minutes and then suicide - and you can't even be revived.

Why not just let animals pick up things with their mouths and/or fumble things around with their paws/talons?

Also, I'd support reverting to human form upon death.
