U1041 - monster hidden under a corpse not displayed immediately when it rots

There was already code to ensure that if a hidden monster moved, it would
no longer be hidden.  However, if the monster is asleep or whatever under
a rotting corpse, when the corpse rotted away, the monster would not
immediately become detected.  Add a check to the rot code before the newsym.
