New map (in progress) and some fixes...

- Now that the MapEditor is more-or-less ready, I started working on a new map. This is currently 'in progress', but it is going to be around 2x bigger than the first map.

- Pathfinding fixed as it turned out it only worked when a path lead to the Main Tower from the bottom. Now it works in all scenarios!

- Minor fixes and an image reference added to the MapEditor to help setting the rotation of path tiles.
