[KS]

- Fix a few bugs in KsPinPropertyHandler & KsTopologyPropertyHandler
[PORTCLS]
- Implement retrieving KSPROPSETID's
- Register KSCATEGORY_AUDIO_DEVICE as a temporary hack untill sysaudio is able to register device interfaces (bug 4556)
Ks Studio is now able to instantiate audio filters on ReactOS
