- Implemented support for the Orthogonal extension into

  both the assembler, and the emulator.

  I finally figured out how I could get support for the
  Ortho extension implemented into the old assembler.

  The only reason for doing this, is to buy me some
  while I start work on the new assembler, and to help
  me get an idea for how to do the same in the new
  assembler.
