* Added VESA capabilities field to the kernel args.

Browse Source 
* The vesa driver no longer uses VGA programming if the chip does not support
  VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
  the new vesa_set_indexed_colors() that is now used for palette programming.
  This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
  hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
  right now, the colors are garbled after a workspace switch. Stefano, are you
  looking into that already?
