  - Add a timer hook to refresh the UART. The debugger will
    look for a symbol named Dosx_call_debugger_every_sec
    before trying to hook interrupt 0x1c.
    Dosx_call_debugger_every_sec is a pointer to a function.
  - Make Ladybug more DPMI compatible.

    percentage is now calculated on total polls instead of the highest
    polls.
