Fix Query Processor Support for Contexts

Bugs

• #229 - Fix (add) support for query processor on the contexts endpoint
• 9c72382 - Ensure request is passed into processor.get_iterable in preview endpoint

Permissions Setting

Bugs

Encoding Bugs

Pagination Bug Fix & Default HTML Formatter

Changes

• Serrano now overrides the default DataConcept formatter with one that includes a to_html method which works better with the /api/data/preview/ endpoint.

Bugs

• Fixed a bug when requesting all values for a field when no values existed.
