SSF : Overlays on the map; project_project controller changes

* Adding hazard, theme, countries to the deployments form
* Permission to anonymous to create task, contributor role
* Deployments, members overlay on the map
* Inline login form
Or even with InlineComponent: better there to use fields = [("", "theme_id")] since otherwise you tend to find knock-on problems elsewhere & need to surround statements by lots of 'if method' which becomes nightmarish to maintain
