 * - call Init_Theater to perform theater-specific inits                                       *
 * - call Free_Cells to free the cell array, because loading the map object will overwrite     *
 *   the pointer to the cell array                                                             *

 * - call Alloc_Cells to re-allocate the cell array                                            *
 * - call Init_Cells to set the cells to a known state, because not every cell will be loaded  *
 * - read the cell objects into the cell array                                                 *
 * - After the map & all objects have been loaded & the pointers decoded, Init_IO() >MUST< be  *
 *   called to restore the map's button list to the proper state.                              *
