Title: Added Tileboard.moveBy()

Added a `Tileboard.moveBy()` method to move pieces by an offset, rather than an absolute ending tile.

The offset argument should look like `{x: m, y: n}` where m,n are integers. This currently doesn't do anything about offsets that would take the piece off the edges of the board.
