The "Now Playing" toolbar now shrinks to fit on small screens. On all
screen sizes, clicking the toolbar reveals a HdyDialog with the same
controls.
Also fixes#158.
The dark theme option is broken with themes that don't ship a
dark variant.
The episode garbage collection doesn't seem useful being
configurable at all.
The gsettings are still there, this just removes the ui
dialog since nothing useful made it into it ever.
Also, less toggles the better.
