Added default distance and default minimum distance in calibration section, already recognized by binaural free field renderer. Also a lot of comments

Fixing manual reset problem for all rendering modules when using a virtual user-triggered sound card. Also adding a VDL before FIR filtering in PrototypeGenericPath to support Doppler shifts, smooth delay handling and sound propagation based on FIR filters for various situations (especially outdoors with fast moving sound sources)

Introducing dual-licensing-style 'selective licensing' in case VACore is build with a dependency to GPL libs (in which case VACore becomes GPL, too)

WIP on offline simulation feature using virtual sound card, currently only working for binaural free field due to a manual reset impl requirement

Starting test-driven development of offline simulation feature using a virtual user-triggered audio device

Temporary fixes in room acoustics renderer, out-of-room detection not working correctly. Could be RavenNet issue

WIP on HATO test and implementation in BFF renderer, still jumpy for near-range-limit HATO HRTFs, problem with index layout or input data?
