Implemented dw_container_set_row_bg() on Windows. Current immplementation is a bit slow, it does more redrawing than necessary... but it works for now... will look to improve it in the future. Also removed a lot of dead code from a previous attempt at implementation. Also flipped the default colors on Mac since the first index is even (0) not odd (1).
