Add a 16-bit pair DLL for TWAIN

[Mike Hearn]

This is probably wrong in some aspects as this is the first time I have
done a 16 bit pair DLL, but the Office XP installer never actually calls
it, it just loads it in order to get the version information.

The main problem is that I can't find way to dump the exports of a 16 bit DLL. 
winedump can't do that. So, as the 32 bit DLL has only one entry point, I assumed
it was the same for the 16 bit version.

thanks -mike
