add a -vga none cli option (Stefano Stabellini)
currently there is no way to fully disable any graphic card device for the PC architecture. You can have no graphical output, thanks to -nographic, but you would have the VGA device connected to your PCI bus anyway. There is already a convenient -vga option to choose between std, cirrus and vmware; this patch add the new option "none" to select no graphic card at all.
