Previously, on every call to updateOriginalInput(), a brand new array of options for every value in selectize.items would be created and the entire HTML string would replace all children of the raw input source. When doing something like selectize.addItems(_.keys(selectize.options)); for a few hundred options, this becomes very sluggish. This takes a smarter approach, only removing and adding individual options from the input source as necessary. The bottleneck is the repeated use of jQuery's html() method with large DOM updates. For ~300 options this was originally taking 30154ms in appendChild. Now it spends only 330.9ms.
