Workflow mockup fixes

* remove "finish workflow" button from object nav
* add "finish workflow" link in "more..." section (where clone workflow is). Functionality is the same
* when task is completed, it should turn blue - not green
* when "finish" workflow is clicked, it should copy final cycle to history. It should also remove "current" widget
