Subject: Version 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.
