* for adding a number of (business) days to the schedule (e.g. "on the rrules' following day")
* fixed a bug for monthly recurrences
* and some minor changes

See #8

See #22 #23

See #21 #23

and:

See #21 #22

...and filters for admin ui and api.

See #21

Changed note filters:
- ?owner=1 returns all notes a user may edit
- ?user=1 returns all notes a user created

See #22

* Users can see and change all notes and hosts of shows they own - even if they were created by another show owner
* A host can be assigned to a note (if host is editable)
* Added django-oidc-provider app
* Added limit/offset pagination to endpoints /shows, /timeslots and /notes
* Common users may not change the show's name anymore via API
* Playout API can be called with start (date) and end (date) parameters
* Added filters to endpoints:

/shows/?host=1  Retrieves shows of a given host
/shows/?owner=1 Retrieves shows of a given owner (= user ID)
/notes/?host=1  Retrieves notes assigned to a host
/notes/?owner=1 Retrieves notes a user has created (= user ID)

Had to set settings const USE_TZ (= reflect timezone in mysql datetimes) to True for OIDC to work with mysql.

Don't know yet if that's a problem.

Shall we still put this in a sub app?
Would still need to figure out how to hook from the sub app into the serializer viewsets (and not vice versa) in order the custom fields get saved.

See #21

Extended Category model with color and description.
Extended Note model with field audio_url, to be able to playback audio files directly in the mobile app.
The field is hidden and will only be used to automatically retrieve the direct file's URL from CBA if the settings variable CBA_API_KEY is set and valid.

See #24

Updating is constrained to defined fields.
See #22

Implemented django-oauth-toolkit for authentication.

Working on prototype for playout API (momentarily still called week_schedule())

Added permission restrictions for common users in APIs
See #23

Added playlist_id to TimeSlot datamodel
See #21

Made some minor changes in calendar.

* Improved note selection: Users choose their shows and corresponding timeslots are loaded into the select via ajax (improvement still necessary to avoid queryset when initially loading)
See #17

* Users can only see and edit their shows, timeslots and notes
* Users can only edit their own profiles

* Changed fallback_playlist to fallback_playlist_id
* Timelots inherit the is_repetition flag from their schedules when created
* Added field 'memo' to timeslots (for internal notes)
See #21

See #21

* Extended datamodel of user profile by introducing "profile"-subapp
* Implemented thumbnail generation for shows, notes and user profile using django-versatileimagefield (see requirements.txt)
