This Widget is intended to be used as the child widget in a Gtk.ListView
to display and change the sort order of the current playlist. I use
arrow buttons from the icon library to represent sort order

This is an ImageToggle button that has been configured to cycle between
3 states corresponding to no looping, playlist looping, and track
looping.
I also update the Tracklist to look for changes in the visible Playlist
to update the Loop button.
