Support alternative servers

[davidvedvick]

As a user, I want to be able to connect to other server formats, such as jellyfin, so that I can use project blue without purchasing j river.

• Jellyfin
• Subsonic
• DLNA?
• Plex API
• Beets
• Lyrion Music Server

[davidvedvick]

• Support/match client API's between MC and other servers as much as possible
  • fun promiseItems(itemId: ItemId?): Promise<List<Item>>
  • fun promiseAudioPlaylistPaths(): Promise<List<String>>
  • fun promiseStoredPlaylist(playlistPath: String, playlist: List<ServiceFile>): Promise<*>
  • fun promiseIsReadOnly(): Promise<Boolean>
  • fun promiseServerVersion(): Promise<SemanticVersion?>
  • fun promiseRevision(): Promise<Int?>
  • fun promiseFile(serviceFile: ServiceFile): Promise<InputStream>
  • fun promisePlaystatsUpdate(serviceFile: ServiceFile): Promise<*>
  • fun promiseFiles(): Promise<List<ServiceFile>>
  • fun promiseFiles(query: String): Promise<List<ServiceFile>>
  • fun promiseFiles(itemId: ItemId): Promise<List<ServiceFile>>
  • fun promiseFiles(playlistId: PlaylistId): Promise<List<ServiceFile>>
  • fun promiseFileStringList(itemId: ItemId? = null): Promise<String>
  • fun promiseShuffledFileStringList(itemId: ItemId? = null): Promise<String>
  • fun promiseImageBytes(serviceFile: ServiceFile): Promise<ByteArray>
  • fun promiseImageBytes(itemId: ItemId): Promise<ByteArray>
  • Allow user to enter credentials, configure, etc.
    • Change library entity to have different configuration settings (via JSON blob?)
  • How to read file properties, images, etc.?
  • classes that will need a version for each server:
    • ConnectionSettings
    • ServerInfo
    • LiveServerConnection
    • ServerConnection
  • library needs to be adapted to store different connection settings
    • library view model will need to be adjusted too
      • maybe a different "sub" view model for each connection type?
