Patch adds jquery quicksearch plugin to views_ui_add_item_form

Get the quicksearch plugin here: https://github.com/riklomas/quicksearch
Extract jquery.quicksearch.js into sites/all/libraries/views/
Apply the patch.

When adding fields, filters etc to a view this will filter the options as you type.

This is mostly just a proof of concept at this point. I'm sure there is a more natural way to integrate this into views.
