Updates mindbender-search to reflect DeepDive's variable table rename

`Q_inference` instead of `Q_label_inference`, and the view now
completely subsumes the original variable table `Q`

Changes repo name for github release

Fixed critical recall mode bug

Mindtagger: improved button colors for precision mode tags

Postgres arrays serialized in CSV were being parsed incorrectly, because
TSV escapes were being incorrectly handled while parsing Postgres
arrays.  Now, TSVs escapes are handled earlier at the backend, so the
frontend receives the same data regardless of the items input format:
CSV or TSV.

Fixes HazyResearch/deepdive#173
