Update JS to latest standards plus add ability to work on TextArea tags

.attr has been depricated and .prop should be used instead. Also, at present this plugin does not work on TextArea tags.

The snippet below can be used as a replacement for the current JS in this plugin. It now uses the latest standard and work on all inputs including textareas.

jQuery(document).ready(function($){
$(“.disabled input”).prop(‘disabled’,true);
$(“.readonly input”).prop(“readonly”, true);
$(“.disabled textarea”).prop(‘disabled’,true);
$(“.readonly textarea”).prop(“readonly”, true);
});
