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
NB this would imply that we track which software they have deployed (Eden or Vesuvius), and potentially whether they are self-hosted or managed, have their own vendor team (e.g. AidIQ) or are based on SSF/community support, whether they use custom functionality (e.g. RGIMS), or a community template etc etc...

I still do not necessarily see the point in tracking this level of detail about the user org activities, while we rather need a basis for use-case statistics as you suggest?
