Fixed buffer overrun for LUA strings

Made direction variables more consistent as unsigned chars.  Several function prototypes updated for this.
Many memory leaks plugged:  External options, video overlays, laptop file lists, tactical message queue, strategic pathing, autobandage, merc hiring, detailed placements, crate in Drassen, tactical placement
New functions and attributes for soldiers in LUA (still for debugging at best): Soldier.APs (current APs), Soldier.changestance (changes stance, uses game heights)
File catalog ignores .SVN directories (game load speedup)
Fix CTD in mouse regions
JA2 window now refuses to move to negative coords
Checks to prevent DirectX-related infinite loops due to minimizing and task switching
Invading enemies should now appear on the borders even when reinforcements disabled in .ini
Suppression should no longer work on mercs in medium water
Infant/Young creatures use restored spit instead of Molotov
Creatures begin with their 'guns' (spit) 'locked and loaded' (cartridge in chamber)
Further fix to AXP and AlaarDB's weapon ready check:  Now 'firing' is always counted as 'ready'.
Prevent mercs from falling and flying back through obstacles
Check whether battle group is even set before testing its location for battle setup
Burst spread locations now limited to 6, the limit within the soldier struct
Extra burst spread locations zeroed out so that they aren't used unless necessary
Spread code now only shoots at locations in the spread, and will shoot at all 6
Only mercs in the sector where autobandage happens will be made to stand up after it's done
Throwing a grenade at the tail of the plane in Drassen should not result in a CTD
Reset attack busy count when loading a new sector
