* @license jQuery UI Multiselect
*
* Authors:
* Michael Aufreiter (quasipartikel.at)
* Yanick Rochon (yanick.rochon[at]gmail[dot]com)
*
* Dual licensed under the MIT (MIT-LICENSE.txt)
* and GPL (GPL-LICENSE.txt) licenses.
*
* http://www.quasipartikel.at/multiselect/
*
* UPDATED by Oleg Kiriljuk ([email protected] ) to support jQuery 1.6 and hight
* (the usage of jQuery.attr and jQuery.removeAttr is replaced to the usage of jQuery.prop
* in case of working with selected options of select)
*
* Depends:
* ui.core.js
* ui.sortable.js
*
* Optional:
* localization (http://plugins.jquery.com/project/localisation)
* scrollTo (http://plugins.jquery.com/project/ScrollTo)
*
* Todo:
* Make batch actions faster
* Implement dynamic insertion through remote calls
