1. fix select options existence predicate …

   - `$el[0].options` would always evaluate to `true`
     even if the select object didn't have any option
     elements. So instead we're checking if the
     length is truthy.
   - `selectedIndex` would evaluate to `true` because
     when there is no selected item `selectedIndex`
     equals `-1`
   
   So in essence, stickit would try to get the
   current selected option value even though there
   were no options. This caused an issue on Internet
   Explorer (tested in IE7 and IE8), where it would
   fail when stickit tried to access the
   `selectedIndex` of the select tag's options array.
