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
Just to make that clear: a "project" of a humanitarian org is related to certain hazards, so you can say "this organisation is doing something about this hazard at this location".

But what has that to do with Sunflower? Sunflower projects (="deployments" in the wider sense) are not about hazards, but about deploying a tool for a either project or an event.

Sunflower itself is a deployment - but what's the hazard? What's the location? The 3W theme?

It seems that by making this 3W, we're actually managing information about the user organisations and what they do - rather than about our community and what we do. Yet the latter was the actual purpose of Sunflower, wasn't it?

Very confusing.
