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
I mean - we're not doing anything about the "risk of floods". But we give people a tool to manage information about organisations doing something about the "risk of floods".

So, the hazard of Sunflower deployments is always "lack of a proper tool to manage information", and the theme is always "Information Management". Why not hardcode it?
