/*
MINOR_MAP_VERSION Log -- Created by Kris Morness, November 14, 1997
Version 0 -- Kris -- obsolete November 14, 1997
	The newly created soldier information had a couple bugs regarding initialization
	Bug 1)	Soldier placements without detailed slots weren't initialized.
	Bug 2)	The attitude variable was accidentally being generated like attributes
			which usually put it completely out of range.
Version 1 -- Kris -- obsolete January 7, 1998
	Bug 3)	New changes to the wall decals, made the currently existing ones in the world
			unpredictable, and are automatically removed, so new ones can be used.
Version 2 -- Kris -- obsolete February 3, 1998
	Bug 4)	Enemy mercs now have a color code assignment which defaults to army.
Version 3 -- Kris -- obsolete February 9, 1998
	Bug 5)	Move entry points down if they are too high.
Version 4 -- Kris -- obsolete February 25, 1998
	Bug 6)	Change all doors to FIRSTDOOR
Version 5 -- Kris -- obsolete March 4, 1998
	Bug 7)	Remove all exit grids (the format has changed)
Version 6 -- Kris -- obsolete March 9, 1998
	Bug 8)	Change droppable status of merc items so that they are all undroppable.
Version 7 -- Kris -- obsolete April 14, 1998
	Bug 9)	Priority placements have been dropped in favor of splitting it into two categories.
					The first is Detailed placements, and the second is priority existance.	So, all
					current detailed placements will also have priority existance.
Version 8 -- Kris -- obsolete April 16, 1998
	MAJOR CONFLICT RESULTING IN A MAJOR VERSION UPDATE 2.00!
	Bug 10) Padding on detailed placements is uninitialized.	Clear all data starting at
					fKillSlotIfOwnerDies.
Version 9 -- Kris -- obsolete April 26, 1998
	This version requires no auto updating, but external code has adjusted the size of the mapedgepoint
	arraysize from UINT8 to UINT16.	See Map Edgepoints.c.
	Bug 11) Convert all wheelchaired placement bodytypes to cows.	Result of change in the animation database.
Version 11 -- Kris -- obsolete May 2, 1998
	Added new center entry point.	Need to initialize the original padding to -1.

	Version 6.27 ADB July 22 07
	Changing the format of OBJECTTYPE means the maps should be loaded, converted, and saved
	if one wants to take advantage of the new format
	Converting to the new format is not necessary to load a map and run the game.
	**Note** this conversion hasn't happened yet
