Fixing formatting due to URI change.

[lovemonkeyz]

As spotify URI format has changed, and sometimes it adds a "?si=string" after the ID (not sure what it does, but if you try to use it in the original program, it throws invalid spotify link error). It won't fix album downloads until the package used is updated, but at least it removes any issues where a copied link contains the ?si= part.

This is a lazy fix, for sure.

• Removed "|| IsSpotifyPlaylistUrl(str)" from IsSpotifyURL
• Removed IsSpotifyPlaylistURL class as it is no longer needed
• Changed IsSpotifyTrackAlbumURL to include playlist
• Added a second delimiter to url.split(), "?" - This way we can remove the sometimes added extra string after the ID of playlist/album/track.

You'll have to excuse the automatic formatting change. Differences in IDE I assume :D.

I have tested the change myself, of course. Building and functionality remains the same.
