Addresses performance issues when rendering selects. Now, in render(), when targeting an element using originalIndex, rather than filtering through every li element (insanely resource intensive), the originalIndex is accessed from an object (liObj) where the key is originalIndex and the value is that option's actual index within the list. Also, where it makes sense, native Javascript DOM properties have also been utilized to improve render speed.
Also fixes liveSearchNormalize as seen in #960.
