- new modifiers "MISS_MAX_RADIUS_x" for grenades and mortar to set a max radius where they will land. Chance to hit something with explosives is now based more on skill than on luck.

Browse Source 
- fixed infinite loop in function "RandomGridFromRadius" when min and max radius were 1
- fixed incorrect exit condition in function "RandomGridFromRadius" when min radius was 0
- fixed incorrect CtH calculation for mortar
