Allow ziggurats placed in Pandemonium to return to the same Pan level when the player leaves the ziggurat. Breaks saves.

Cleaned up up_stairs() and down_stairs() to remove spurious depth changes when changing you.level_type - depth (you.your_level) now changes only for stairs with both ends in LEVEL_DUNGEON.

All levels are now saved on exit, including non LEVEL_DUNGEON levels. Re-entering non-dungeon levels from down_stairs will still delete the old level. Re-entering non-dungeon levels from up_stairs (i.e. returning to a non-dungeon level from some other place, like a ziggurat) will reload the old level.

Fixed bogus marker trashing when player attempts to use a Zot entrance with insufficient runes.

Delete .msg files when game ends.
