- Implemented the multiply expression into the assembler.

- Implemented support for the SIB addressing mode into
  the assembler.

  SIB is short for "Scale Index, and Base", and works
  much like x86's version of SIB (scale*index+base),
  although my version supports any scale value between
  1, and 256.

- Redid the line shifting routine in SuBEditor.

  It now uses memcpy, and memset to do that, and also
  supports shifting the line left, or right by any
  number of characters.
