Do not cache results from initial query

Trying to bust any caching that might be happening on iOS devices pre-iOS7. Employing two strategies here: altering the URL to include a timestamp parameter and passing ``{ cache: false }`` as an additional option to ``$.ajax``.
@sarenji yeah. technically i think  you're right. practically i'm pretty sure it's not possible for a URL to have the query string be at ``index = 0`` or even ``index = 1`` for that matter.
