MongoDB search is pretty meh. This branch is the first stab at leveraging Elasticsearch. More about Elasticsearch here: http://www.elasticsearch.org

Experiment adds `query` and `search` params to Entry#findByParams (supported in both templates and REST API). `query` defers to Elasticsearch's "simple query string" (better for filtering/templates), while `search` uses a "fuzzy" query with some simple defaults (better for autocomplete). Ended up using query for the typeahead anyway (adding a * to the end by default).

Add Entry#fetchWithParams and typeahead.js to frontend, and a quick demo to the dashboard.

Issues:
* Currently setting query or search will override and ignore all other params sent in. If people like this approach, we should port the function altogether to rely on Elasticsearch. (would be pretty straight-forward)

Still uses a timeout though :/ just want to try on Travis

Start to fill in Buckets route tests a bit

(and start a "prep" which waits for Mongo connection)

Discussed Model#refresh with mongoosastic contrib. Unfortunately still requires a timeout after initial indexing/refresh. Adds more tests.
