B804: Put the scene's objects in the object records
Used by the routine at GAME_ENDED.
From the first record on, one record for each five-byte entry of the list at DE until a zero: the graphic to +0, the flags to +7, the colour to +10, and the place on the screen to +1A and +1B, x and line of the buffer. The scene's update routines draw from there and colour what they draw with +10 (the second entry of SCENE_SPARKS). The records were cleared before (CLEAR_OBJECTS).
