AI improvements

Browse Source 
AI will no longer skip turns with heroes that are waiting for a delivery that takes more than one turn. Instead they will do something until their delivery is close enough to get it at the same turn.

Fixed an issue where a bunch of heroes all tried to do the same tasks:
Tasks that involve no fighting will now always be performed by the closest eligible hero while all other heroes look for something else to do.
