Improve PlaybackManager stability, added PlaybackBar

Browse source 
- PlaybackManager now takes ownership of set items
- PlaybackManager can play items just by their itemId, avoids useless
  item creation on the QML side of things.
- Allow calling Jellyfin::registerTypes with a different URI
- Minor code cleanup
