playQueue: Finished refactoring

Bugs fixed and features:
 - Creating the database and adding songs in the same run would fail
 - Songs with multiple artists are now separated with ', ' instead of the ID3 ';'
 - Excluded .mp4 files from the song list
 - Songs aren't scanned and duplicated on every start
 - General cleanup and memory leak fixes
