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
Which Classification of regions/sub-regions are we planning to use?
(Every org has their own way of cutting this up...I'm surprised that SSF thinks it needs to split regions into a hierarchy as we're rather a small org ;) )
