[ion] 20366: - Added support for NTLDR style freeloader GUI. To enable, edit freeldr.ini and add:

- Added support for NTLDR style freeloader GUI. To enable, edit
freeldr.ini and add:
ShowTime=No
MinimalUI=Yes
MenuBox=No
CenterMenu=No
TimeText=Seconds until highlighted choice will be started automatically:
Also make sure the following are set:
MenuTextColor=Gray
MenuColor=Black
TextColor=Gray
SelectedTextColor=Black
SelectedColor=Gray.
- Also made the boot-up screen black, not blue, since that's the actual
color it's been after NT4. If booting without NOGUIBOOT, this results in
a much nicer transition to the boot screen (especially if using the
NTLDR theme)
- Some other minor changes done to simplify transitions while booting.
Hoping for filip to finish his Bootvid patch to remove the last annoying
gui->text->gui switch near the end :).
