selectize.addOption() only called once for entire options array

I moved everything from `objectWasAdded` into `contentArrayDidChange` because it makes the plugin work faster and because `selectize.addOption()` only needed to be called once. While this works for me, I'm not confident that I haven't missed anything. If you have time, throw your suggestions my way and I'll update. Cheers!
You're right. I guess I was a bit hasty in my attempt to resolve my issue. My patch seems to work for me, but I may have only been addressing symptoms.
