This PR allows imported data to also be associated to one or more areas based on a CRM field, as well as the pre-existing point geography (from an address or postcode).

The user defines what kind of area (a constituency, ward, or council) and then the text string fuzzy matches against the database of areas.

This will allow us to query events and other imported entities against constituencies, even if they don't have a pinpoint location: for example, online events.
