Upgraded v3.1 to jQuery v1.9 + jQuery Migrate. Also implemented jquery-ie.min.js and jquery.min.js to support a future split between IE7/8 and modern browser where IE7/8 would remain on jQuery v1.9 and modern browser would proceed to jQuery v2.0+. jQuery Migrate is only intended as a temporary measure to assist with the move to jQuery v1.9 and jQuery v2.0.
