🐛 Bring in blacklight_range_limit js files

When we have the blacklight_range_limit require in the application.js
before the require for blacklight/blacklight, we got a Blacklight not
found error (underestandably).  However when we put it under the
blacklight require then we got a typeahead error.  I couldn't get both
to work right so instead I'm bringing over the js files from the range
limit gem into our app and requiring them in the application.js.
