LP#1411699 Dojoless advanced copy location search

We still use OpenSRF to make the request, but now use the URLSearchParams API +
polyfill for CGI parsing.

URLSearchParams is a browser API implemented on Chrome, Firefox, and Safari,
and a polyfill is available for IE etc from
https://github.com/WebReflection/url-search-params.

This lets us avoid loading Dojo and just rely on the core, much smaller OpenSRF
JS libraries to communicate with the server.
