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.
