Now the playback state of a stream is loaded only when needed (i.e. when the stream is visible), just as it is done with thumbnails.
Removed `StateObjectsListAdapter.java`, which used to load the state of every stream at list instantiation, generating slowdowns and freezes.
-Changed play queue items to display service names.
-Fixed Soundcloud playlist not fitting thumbnail.
-Refactored image display options to follow uniform behavior.
-Refactoring and style changes on audio reactor and media button receiver.
