flickity tries to use jQuery Deferred function even if jQuery doesn't support it #846

Consider a legacy website where jQuery 1.4.4 is loaded before flickity. Using imagesLoaded: true option results in error Uncaught TypeError: $.Deferred is not a constructor as flickity finds $ and does not check if Deferred function is available. Would be nice if flickity did additional check to see if Deferred function is actually available or even option to force disable jQuery usage.
