couple of #wizintrinsic fixes

When #wizinstrinsic was expanded to be able to set any timed attribute,
some that need more than just a timeout counter were left inconsistent.
1) Timed Flying wasn't blocked by levitation, and existing flight
   wasn't becoming blocked by timed levitation.  Also, eventual flight
   timeout wasn't updating the status line, so false 'Fly' condition
   remained shown until a status update happened for some other reason.
2) Setting timer for Warn_of_mon didn't set up any type of monster to
   warn about so wouldn't do anything.  This sets that to grid bug
   unless already set due to polymorph form or artifact that warns.

The end.c portion is just a bit of formatting.
