Lazy loading and optimisation

[johnadamsDFID]

We need to optimise the way we do searching and filtering (applied to the search result and country project list pages).

At the moment the faceted filtering operates on hidden fields and a bunch of JS, but that requires the full page to be populated in advance, and (as another issue highlights) that can take a while.

I'd like to explore patterns that allow us to do lazy loading of the actual content, while being able to filter on the right attributes. I'm sure it's been done before!
