If you kick something while in the air (i.e. on the Air level or while
in a bubble on the water level), 1) greased objects were treated specially
and 2) messages were given about the object sliding.
- add checks for kicking in the air, and always increased distance a bit
(I didn't add any checks to deal with the transition from air to water or
visa versa)
- don't set the flag that causes the "slides" message in these cases either
tripping over a cockatrice corpse didn't petrify, even when not wearing boots
do not call swamps on the Juiblex level "moat" when freezing
keep score from wrapping around and becoming negative by capping it
+kicked objects do not slide when on the air or water levels
