Clear on Polymorph

Clear on Polymorph intrinsics will be removed from the original creature on polymorph. This is not to be confused with Survive Polymorph, in fact they can be set to strange values for interesting results.

For instance, if you have the Confused intrinsic, and polymorph into a new form, the new form will still be Confused but the original form will have it removed. Although, the Confused intrinsic is set to survive unpoly also, so it'll be transferred back to the original form when you unpolymorph.
