Results page now includes method for switching to "All Languages" from whichever language is specified as the primary in the config (see #74). Also removes the non-Whoogle links from the page footer, leaving only the page navigation controls Added support for the date range filter on the results page, though I'd still recommend using the ":past <unit>" query instead.
