- Added cap_net_raw to the capabilities that are not dropped (thanks to Dominic Evans).
- Fixed setting the start time of an edited recording (thanks to Christoph Haubrich).
- Temporarily switching free devices to transponders in order to have their running
status updated is now done by marking the devices as "occupied" for a certain
amount of time.
