Actions: Fully working 2D pathfinding code, including doors.
Added NPC actions so that it now closes doors after opening them. Fixed rotations for opening/closing doors and for reaching the goal point. Added full support to cottages mod gates and half doors. WIP: Support for cottages beds and sleeping mats.
