pass the position in as parameter on new tile creation. remove unnecessary setPosition() function, as tiles no longer really get moved. they get drawn in their div and then the div moves around. no need to make that any more complicated. update tests for that. Also, finish renaming 'grid' to 'layer' (from r369).
