Log:
[NTVDM]
- Fix palette setting for EGA modes, fixes Rescue-Rover menu colors amongst others.
  Some of the palettes were adapted (read: translated from DAC registers settings) from
DOSBox;
  and I've also used http://www.brokenthorn.com/Resources/OSDevVid2.html for some
settings.
  This should be reviewed to fix / remove redundancies or errors.
- Attempt to implement basic palette enablig/disabling flag (via AC palette regs).
- I've introduced (commented) DbgPrint's for testing AC regs setting. I will
remove them when everything is ok.
