The copyright field is now saved as non-existent dcterm:copyright field rather than dcterm:rights. It concerns the metadata editor, the schedule und upload UI.
Steps to reproduce:
1. Start to edit an episode or schedule/upload a new recording
2. Fill the copyright field.
3. Save it.
The copyright field is saved as copyright term in the episode catalog.
The copyright field should be saved as "rights" term in the episode catalog.
