Version 0.03vdr_osm-0.03
- Actual record/replay now works. - Dropped the idea of different "recording qualities" (a 36GB harddisk is able to store some 18 hours in full quality, so we don't really need that). - Termination signals are now caught and the program cleans up before exiting. - Support for CICAM.
