[Feature]: Implement Spotify Jams (when Spotify supports it via the Web API)

[maxrdz]

With one of the goals of this project being full feature parity with official clients, Spotify Jam support is definitely in the list of todo features for this client.

Before you reply, yes I am aware the Spotify Web API does not support jams yet. I thought of posting this issue to bring this future feature to the community's attention so they can vote for the feature in the Spotify community site.
