[Feature request] Add the option to stop recording in the planner

[Gert-Boers]

In the recording planning (sorry, translated from Opnameplanning in my Dutch operating system language) there are only the options Start and Pause. I would love to see the option Stop, which closes the recording properly.

About 5 minutes after a recording, I schedule my computer a shutdown, which leaves the recording with a premature file ending.

Thanks, by the way, for this great feature of planning a recording!
