Link to tasks panel in notifications

* Adjutant-UI now supports views for Tasks, we should link to
  it in the default notification templates.
* To make this possible, and other potential uses, deprecate
  the TOKEN_SUBMISSION_URL in favor of HORIZON_URL
* clean up some formatting issues with the notification template
