workflows: AMD compatible and flightJS

* Refactors all Holding Pen JavaScript to be fully AMD/requirejs
  compatible.

* Rebuilds Holding Pen based on the flightJS framework to render
  the Holding Pen table and details pages, in addition to actions.
  This includes many changes to the static files and the interface
  itself - removing unused and non-working elements of it.

* Adds translation support to the predefined status tags for the tags
  interface in Holding Pen. This changes the bower requirements to use
  INSPIRE-HEP fork of bootstrap-tagsinput to support this functionality.

* NOTE To get the new version of bootstrap-tagsinput delete your
  existing bootstrap-tagsinput vendors and static files and folders and
  re-run `inveniomanage bower -i bower-base.json > bower.json` and
  `bower install` from the overlay.

* Refactors the bundles to accommodate these changes in addition to
  adding missing CSS used by DataTables.

* Improves the default approval action to fade out after an action
  was completed successfully.

* Adds dependency of datatables-tabletools plugin to provide selection
  by replacing the former in-house implementation.

* NOTE this update changes the global settings.js file which means
  that you need to update your version on the overlay in
  case you were required to override it with your own settings.
