* technically it should only effect the visibility of tiles when you're
exploring on the world map.
Fixed the incorrect coordinates for small/medium location circles when
highlighting their sub-tiles (one of bugs listed in #228)
Moved the fix for the position of the target marker from Worldmap.cpp to
BugFixes.cpp.
Slightly adjusted the position/size for Local variables button in debug
editor.
* Mainly for fixing the issues with CheckWeaponAmmoCost. Because it's
easier to backport the whole set of code than working on the old
implementation. Shouldn't affect the performance much.
Also backported the CheckWeaponAmmoCost code from 4.x.
Updated hookscripts.txt to reflect the change.
Now the debug editor starts at the center of the screen.
