Fix some bugs in the setting and tracking of is_confidential as state changes on Issue and Proposal.
Updated some views to use AjaxFormView's reload_on_success API. This is required for visual reaction after saving an Issue or Proposal with a change of state in regard to confidentiality. The app does not (yet) have any type of UI binding, so page reload is the best current solution.
Pass community to initialize forms with a filtered set of confidential reasons.
