Big changes.

Created a new playlist "class" that can be instantiated and used to
store playlists.
Interface stuff is really just a prototype but it works well enough.
Need to add the ability to add tracks to playlists that have already
been created.
So much shit

I don't even know. Doesn't work 100% yet
Playlists Update

Can now add tracks to plalists that have been created already.
More Playlist shit
idk what this is
