Merging changes from master
Cleaned up pathrind a bit.  Test cells against the blacklist (blacklist of coordiates) and impassible (blacklist of tiles) sets.

Added pathfind_evenr, which accepts normal coordinates.

Default cost of cells to 0.

Make a quick default path just for demonstration purposes.
