UI: Task & Execution screen refactored

* code view is now a public template
* emptyform is now a public form

* tasks overview screen
  * add state info field
  * add iso filter to time fields
  * add workflow link
  * refactored detail layout

* tasks main screen
   * main table now has result and
      published columns which use the
      code view template
