Scan algorithm overview: For each changed: Get all files from DB that starts with the folder, scan each file:

	    if file in folder is newer, update the one in DB
     if file in folder does not exists in DB, add
	    for each file in the DB that is not found in the folder, delete from DB

For each deleted folder: delete all files from DB that starts with the folder path Create new albums/artists, update counters:

     collect all albumIDs and artistIDs from previous steps
	    refresh the collected albums and artists with the metadata from the mediafiles

Delete all empty albums, delete all empty Artists
