[KS]
- Partly implement pin property handling by using supplied pin descriptor properties
- Dynamically allocate connection format and put in pin's object bag
- Remove bogus assert as pins don't have to provide a PinDispatchCreate function
- Tuner device filter and capture device filter now successfully connect and instantiate
corresponding input / output pins
