Subject: [PATCH] Remove LOADER from MAZE.

The LOADER subroutine breaks MAZE because it pushes all code higher,
making constants and WALLS cross over 14000.  It's also unnecessary
since setting the start address to 101 jumps back to SSV which will
accept the next data block sent from the PDP-10.

A possible explanation is that LOADER was added by someone running
MAZE without SSV.  No other version of the MAZE source code has
LOADER.
