Add a way to help streams visualize what is in queue

This is a feature request suggested by a user. I'm not really sure how to do it, but I am willing to try.

I think that the best way to do this might actually to be a Browser Source to use in OBS. There's no good way of adding a chat option like !queue or whatever because this isn't a chat bot. I could put the queue on the site, but that makes me think that just don't the browser source is the best way to implement it. This might be dependent on doing the UI revamp of separating out the UI code in #181.

This did not depend on the revamp. Am working on this right now

[SaxyPandaBear]

This is done. I can work on making it look nicer, but not really interested in that right now

Reopening this because I need to revisit it at some point. The main issue with the original implementation was that it just simply read the user's Spotify queue and regurgitated it with disgusting looking HTML. I think that a player's queue is technically derivable by querying from the messages table, filtering for successful messages by broadcaster ID, and then using the timestamp to derive the spot in the queue, but I don't know how inefficient this is, or how badly it would turn out. I think it's worth trying at least.

Another thing I could do is actually just implement a chat bot and then have that respond with the user's queued songs. I have had separate feature requests for a chat functionality and a visualized queue, so not sure which makes the most sense.
