[python-win32] Access COM object thru other than default interface

[Jens B. Jorgensen]

It's been a while since I've done exactly this but I think what you want 
to do is create an IBBBObject passing the object reference to it as a 
parameter. I think you'll need to be using the makepy'd module for this 
but I notice you are creating the object through Dispatch rather than 
the module. Are you not including a makepy'd module?
