/***************************************************************************
	KEN'S TAG DEFINITIONS:      (Please define your own tags for your games)

 sector[?].lotag = 0   Normal sector
 sector[?].lotag = 1   If you are on a sector with this tag, then all sectors
			with same hi tag as this are operated.  Once.
 sector[?].lotag = 2   Same as sector[?].tag = 1 but this is retriggable.
 sector[?].lotag = 3   A really stupid sector that really does nothing now.
 sector[?].lotag = 4   A sector where you are put closer to the floor
			(such as the slime in DOOM1.DAT)
 sector[?].lotag = 5   A really stupid sector that really does nothing now.
 sector[?].lotag = 6   A normal door - instead of pressing D, you tag the
			sector with a 6.  The reason I make you edit doors
			this way is so that can program the doors
			yourself.
 sector[?].lotag = 7   A door the goes down to open.
 sector[?].lotag = 8   A door that opens horizontally in the middle.
 sector[?].lotag = 9   A sliding door that opens vertically in the middle.
			-Example of the advantages of not using BSP tree.
 sector[?].lotag = 10  A warping sector with floor and walls that shade.
 sector[?].lotag = 11  A sector with all walls that do X-panning.
 sector[?].lotag = 12  A sector with walls using the dragging function.
 sector[?].lotag = 13  A sector with some swinging doors in it.
 sector[?].lotag = 14  A revolving door sector.
 sector[?].lotag = 15  A subway track.
 sector[?].lotag = 16  A true double-sliding door.

	wall[?].lotag = 0   Normal wall
	wall[?].lotag = 1   Y-panning wall
	wall[?].lotag = 2   Switch - If you flip it, then all sectors with same hi
			tag as this are operated.
	wall[?].lotag = 3   Marked wall to detemine starting dir. (sector tag 12)
	wall[?].lotag = 4   Mark on the shorter wall closest to the pivot point
			of a swinging door. (sector tag 13)
	wall[?].lotag = 5   Mark where a subway should stop. (sector tag 15)
	wall[?].lotag = 6   Mark for true double-sliding doors (sector tag 16)
	wall[?].lotag = 7   Water fountain
	wall[?].lotag = 8   Bouncy wall!

 sprite[?].lotag = 0   Normal sprite
 sprite[?].lotag = 1   If you press space bar on an AL, and the AL is tagged
								  with a 1, he will turn evil.
 sprite[?].lotag = 2   When this sprite is operated, a bomb is shot at its
								  position.
 sprite[?].lotag = 3   Rotating sprite.
 sprite[?].lotag = 4   Sprite switch.
 sprite[?].lotag = 5   Basketball hoop score.

KEN'S STATUS DEFINITIONS:  (Please define your own statuses for your games)
 status = 0            Inactive sprite
 status = 1            Active monster sprite
 status = 2            Monster that becomes active only when it sees you
 status = 3            Smoke on the wall for chainguns
 status = 4            Splashing sprites (When you shoot slime)
 status = 5            Explosion!
 status = 6            Travelling bullet
 status = 7            Bomb sprial-out explosion
 status = 8            Player!
 status = 9            EVILALGRAVE shrinking list
 status = 10           EVILAL list
 status = 11           Sprite respawning list
 status = 12           Sprite which does not respawn (Andy's addition)
 status = MAXSTATUS    Non-existent sprite (this will be true for your
			code also)
