DeckLinkSrc Element for windows

[Josh Doe]

Hi William,
I have begun converting the element to WIndows, but am new to COM so
it is taking me a little while. I believe the only elements that use
COM are the DirectShow ones, so I've copied the initialization code
from there. I'm also new to to MIDL, so I had to read up on that and
convert the IDL file provided by Blackmagic to a header file. I'll try
and work on it more this week so hopefully I can get something out for
you to test.
