Create a seperate ActionHeader object for headers with actions attached alongside a new viewholder to accompany it.
This allows action headers to be created easier without creating your own viewholder.
Change the loop behavior to something that is actually sensible,
with [ ] looping the whole playlist and [ 1 ] looping the song.
This also removes the "Do on end" setting. A new stop option may
be reintroduced, however.
This resolves issue #13.
Update the structure of the settings system to do several things:
- Finally use int preferences everywhere instead of the mix of strings & ints from before
- Create a new preference named `IntListPreference` that enables the use of integers in list preferences
- Actually centralize array values and default values into a single integers xml
- Isolate all the new migration code into a single file
- Refreshed the int tables used by data objects [DB version has been updated, will not update when other changes]
The only preference not migrated is doAtEnd since that is being planned to be retired in a future LoopMode update.
Completely refactor the blacklist dialog to not only use the Storage Access Framework, but also to completely eliminate the material dialogs dependency.
Fix an issue where the playback restore process would only search the list of songs for the currently playing song, running the risk of picking the wrong song with the same name.
Add some [Likely broken] german translations using a mix of other sources, my own knowledge, and a english-deutsch dictionary. Ill try to improve these as I go along as theyre the only ones that I'm really able to translate.
Make it so that PlaybackStateDatabase stores the item data for PlaybackState/QueueItems as strings instead of ids, as ids are too volitaile if the music library changes.
