path to location we think is closest to the goal and we can reach if the goal if goal is unreacahble
-fixed bug crashing bug if you told 2 of your own units to talk to the same place at the same time
-units stop animating when they stop moving
-increased siterange for mage and knight
-added attackrange (but don't use it yet)...if enemy units fall within this range the unit will path to them
fixed bug where units would path really slowly if they were trying to move to the same place
