got images up and drawing.
Mostly working, errors with move method on board
Fixed an issue in the Board Class that arrayList.IndexOf(object) didn't work with type int

also updated BoardTest, and made some small changes to the TileManager.

The rest are misc android files.

We need to fix that.
Missed an update to the TileManager
Merge branch 'board_fix' into solver_libgdx
