Johannes Anderwald 57103f1233 [KSPROXY] 
- Silence traces in IEnumPins interface
- Partly implement IKsObject interface for COutputPin
- Retrieve pin communication and pass it to constructor of CInputPin
- Implement IKsPinEx and IMemInputPin interface for CInputPin
- The DVBT network provider can now connect to the BDA Source Filter
