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 would be interested in their use-cases yes: which modules & the way in which they're using them (preparedness vs response, long-term community building? Is this crowd sourcing? etc)
The 'what sector/themes are the users working in' is only useful for a 'report', not practical action & I am only after the practical bits.
