 * Revision 1.8  1994/09/25  23:40:52  matt
 * Changed the object load & save code to read/write the structure fields one

 * object structure can be changed without breaking the load/save functions.

 * incorporated into the object array.  Also, timeleft is now a property
 * of all objects, and the object structure has been otherwise cleaned up.
