Found finally a program that writes to VGA controller using outw.
Seems that the program thinks that outw acts like two outb:s
that write first to low address and then to high address.
Also added support for outl using the same logic, even though it is
highly unlikely that any program uses that.
Changelog:
VGA emulation now supports outw and outl.
