Version 1.1.0

This is a fairly simple release. I just added some error handling to check if there's a current Spotify session going on, since if there wasn't it used to generate huge error messages. It now has a simple error message as opposed to the previous line of text. Some error messages are automatically printed by the Spotipy Package, while others are handwritten by me. I'd rather them all be handwritten since the end user doesn't need to know about HTTP Requests, but I really don't feel like muddling around with Spotipy.
