PATCH: MSDOS VGA mode

[Marcus Meissner]

Hi,

VGA Display from DOS programs was broken, since ddraw no longer creates
new windows.

This patch fixes it, tested with Monkey Island 1.

However, Monkey Island does not appear to get <return> presses. I see
in 60 returning scancode 0x1c (and 0x9c on release), but it never triggers
any reaction :(

Ciao, Marcus

Changelog:
	Made DOS VGA display again with last months DDRAW updates.
