  and simplifies the accompanying js file.

* Removes much unused or unnecessary code including unfinished
  actions and the few defined WTForms fields that are no longer
  used

  merging the /actions and /details view into one page (details).

* Updates Holding Pen js files to no longer have hard-coded
  references to the "approval" action.
