Function shuffle_tiles

src/o_init.c:34–50

Shuffle tile assignments to match descriptions, so a red potion isn't * displayed with a blue tile and so on. * * Tile assignments are not saved, and shouldn't be so that a game can * be resumed on an otherwise identical non-tile-using binary, so we have * to reshuffle the assignments from oc_descr_idx information when a game * is restored. So might as well do that the first time instead of

 * another routine.
