 * not call a player_*() itself (i.e. for dropping a bomb). this will be
 * done with the player_*() functions which should be called only from the
 * game_loop();
 *
 * direction keys will set the moveing state (player->m) and the direction 
 * value (player->d) the bomb and special key will set a special flag this
 * the values will be used in player_loop () and the flags will be reset in 
 * there too.
