Title: Update deprecated form selectors (:file, :radio, etc.)

Shorthand form selectors in jQuery such as :file, :radio, :checkbox and others have been deprecated. I've replaced any instances with the standard type which has always been supported and provides better performance for modern browsers. For example, :file now is input[type=file]. There are a few instances in where attribute selectors were already used so I stuck to the same format of no quotes on the attribute value.
