Very simple plugin.

Usage:

<script type="text/javascript" src="rfwadmin_files/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="rfwadmin_files/jquery.escape.js"></script>
<script type="text/javascript">alert($.escape('&<>"\''))</script>

I am not sure if the $.escape = $.prototype.escape = function(...) is the official jquery way of defining a method called without a context. Seems to work.
