* Moved VGA planar mode blitting into the VESA kernel driver.

* In grayscale mode, the AccelerantHWInterface now sets the palette correctly.
* HWInterface now has a fVGADevice set by AccelerantHWInterface which will be used
  to talk to the VESA driver.
* Completed planar blitting for all 4 planes; we now have a perfect 16 color
  grayscale mode when you choose "Standard VGA mode" in the boot loader with
  an unsupported graphics card (such as in Qemu).
