AI flanking improvement by Sevenfm:

Browse Source 
Improved AI RED/YELLOW flanking:
 - better direction calculation (use direction arrays)
 - increased search range 4->8
 - removed incorrectly calculated AP limit (use CalcActionPoints instead)
 - additional direction for flank spot searching
 - prefer desired direction
 - penalize tiles with no cover from noise location
 - penalize tiles too far from noise location
 - don't go into deep water for flanking
 - skip water tiles (can flank over water tiles only if can cross them in one turn)
 - min/max flanking range depends on time of day and base sight range
 - skip buildings when searching for flank spot if not in building already, because soldiers often run into buildings and stop flanking
 - use RUNNING movement mode for flanking instead of default SWATTING
 - only CUNNINGSOLO and CUNNINGAID soldiers flank
 - don't start flanking when no friends between soldier and noise gridno (in 3 directions)
 - stop flanking when no friends between soldier and noise gridno (in 3 directions)
 - stop flanking and reset flank counter in BLACK state
 - avoid map edges when flanking
 - disable flanking for soldiers with limited roaming range (STATIONARY/ONGUARD/CLOSEPATROL/SNIPER)

 In general, AI flanking is much more effective now (it never fully worked previously, especially in turnbased).
