Ben Busby 4324fcd8f8 Added better multilingual support, updated filter
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.
