* jQuery TinySort 1.3.27
* A plugin to sort child nodes by (sub) contents or attributes.

* michael.thornberry@gmail.com
*
* Usage:
*   $("ul#people>li").tsort();
*   $("ul#people>li").tsort("span.surname");
*   $("ul#people>li").tsort("span.surname",{order:"desc"});
*   $("ul#people>li").tsort({place:"end"});
*
* Change default like so:
*   $.tinysort.defaults.order = "desc";
*
* in this update:
* - replaced pushStack with actual replace so initial jQ object is reordered (not only the returned object)
*   - fixed non-latin character ordering
*
* in last update:
* - removed isNum
*   - fixed mixed literal/numeral values
* - refactored fn contains()
* - revision number now corresponds to svn revision
*
* Todos:
*   - todo: uppercase vs lowercase
*   - todo: 'foobar' != 'foobars' in non-latin
*
