Basic rendering of data

Rendering a stupid simple query, on a stupid simple HTML template, from actual Elasticsearch.

TODO before merge:

- [ ] Make a mapping for proper `not_analyzed` and highlighting options on `ig_reports`.
- [ ] Configurable search query.
- [ ] Display basic count/page data, just as a proof-of-concept.
- [ ] Task for managing ES indices -- POSTing the mapping, DELETEing the mapping or the index, etc.
- [ ] Get it running on production.

After this, the next stage (PR) will be to make a sketch and embed it, of what the site's homepage should have and contain. It should be just-barely-acceptable. A search form on the main page, and a link for each inspector to a list of all their reports. There'll need to be a way to figure out the unique inspectors in the system, and a way to list/handle unreleased reports.
