* There is one database for each Server
* Index items are saved with a "musicFolderId" prop, which makes it possible to filter the database by musicFolder without necessarily having to query the server for it.
* Databases for new Servers are created on the fly
* If the user removes a server, the respective database is deleted.
* CallResponseChecker functionality are now Kotlin Extensions
* Removed unfitting shortcuts from SubsonicAPIClient
* Increase timeout to get a video url
* Fix a bug, that the Rest API version was checked twice on each call
