v0.4.0

Note: This version was yanked, because a corrupt package was uploaded and failed to install.

This is a polishing release, adding a few little extras and improving on many others. We had to break a couple of API's to do so, and therefore bumped the minor version number. v0.4.x may be the last in series before we migrate from the current channel-based Spotify backend to a more HTTP-based backend. Targeting that major effort for a v0.5 release sometime, we intend to maintain v0.4.x as a stable branch until then.
