Combat

Reworked surround bonus. Outnumbered effect halved. New Surrounded bonus if you have guys actually on the other side of the enemy. Hopefully this will help make the game a bit more about manoeuvre and tactics.
To get this bonus you need an ally opposite (i.e. on the other side of the defender) - or in a space adjacent to this. (while still adjacent to the enemy)
New AI to deal with new "surrounded" bonus.
Expanded leadership. Killing an enemy leader will result in a bigger than normal morale drop to surrounding enemies. Good leaders now have an aura, providing a small combat boost nearby.
Both these rules apply to your party members too!

Misc

Improved some combat animations
Improvements to dungeon map (the narrow corridor one won't be picked if there are too many combatants)
Add specialisation route to F2 info screen (e.g a rogue can become a ninja, assassin, etc)
Show weapon specialisation group in tooltip
Cut down on early "elite" variants of enemies, as these are a bit too difficult
