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
Case is here: 
https://github.com/nursix/eden/commit/8660e4dcd673f3a13eec67a86c0f670b5ac3b344#diff-9bd6b33d7420bb7d9e0c2c7e2f2cd606R1785

...and fix is here:
https://github.com/nursix/eden/commit/8660e4dcd673f3a13eec67a86c0f670b5ac3b344#diff-66e8d33b478f010c26ff8902d41845a1R976

With settings.project.projects=False, this could not happen (since no join to project_project needed in that case).

Thanks for the nice test case!!
