- Bugfix: AI acts strange (does not shoot out of weapon range, ...) when NCTH is enabled

o AICalcChanceToHitGun the change to hit is reduced to zero if the AI exceeds the gun range by 10% and is only 50% when in that range. 
o I've changed that code to use externalize the parameters to the CTHConstants.ini file. 
o The result is no change in how actual code runs but now those hard coded parameters should be modifiable.
