Adding Bootstrap-Combobox

Hi Robb,

I've added the completed combobox plugin here. I've also updated the bower package to include it. There's only one major issue with the plugin we chose: for some reason, it doesn't render a disabled select form element into a disabled custom combobox. Currently, a disabled select form element renders an ENABLED combobox. You can see it in action on the test page. It's likely that we'll be able to alter the javascript so that it will render a disabled combobox, but I wanted to check in with you to see if that's a worthwhile path to take, or if we should just look for an alternative combobox plugin.

Please let us know what you think.

Thanks,
Susanne
