prepared basic ground for A* pathing
Abandonned having a binary system for, will first get it to work with
two sets of tiles depending on Dijkstra/A*, made preps for it
cleaned up both type of pathfinding tiles
faced with a problem with linking map tiles to pathfinding tiles, so
stopped for now, did however bring most of everything from my demo
project to this one
finished the A* part except for the fact that it doesn't return a path
fixed a few bugs with AStar and implemented findClosest (Dijkstra)
