Fix #173 (a track cannot be played with librespot)

Browse source 
Some tracks might have several `allowed` fields, librespot assumes that all fields must match, otherwise track cannot be played.
This change collects all `allowed` and `forbidden` lists, then does the final check on whole lists at once.
