Fix double click event propagation

This fixes an issue where attempting to rapidly remove songs from the
queue would cause them to be played.

- When clicking the add/play/remove/star buttons quickly, the double
  click event would propagate and start playing the song
- Fixed by extending the `stopEvent` directive to accept a
  comma-delimited list of events to stop. This allowed for using
  `stop-event="click,dblclick"` in the html to not propagate both click
  and double click events.
- Also removed some duplicate directives that seemed to have snuck in
  during a merge.
