[Plugin: Copy in clipboard] Now compatible with WP 3.3

I modifed the below code to be compatible with 3.3. It was throwing an error about calling wp_deregister_script incorrectly.

<?php
/*
Plugin Name: Copy in clipboard
Description: Small plugin that copy text into clipboard (onClick) from title tag using zeroclipboard.

*/

add_action('wp_enqueue_scripts', 'my_scripts_method');
function my_scripts_method() {
	wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js');
    wp_enqueue_script( 'jquery' );

	add_action('wp_head', 'copyinclipboard', 15);
    wp_register_script( 'zeroclipboard', WP_PLUGIN_URL . '/copy-in-clipboard/zeroclipboard.js' );
    wp_enqueue_script( 'zeroclipboard' );
}

function copyinclipboard() {
echo '<script type="text/javaScript">
ZeroClipboard.setMoviePath( \''. WP_PLUGIN_URL . '/copy-in-clipboard/zeroclipboard.swf\' );
jQuery(document).ready(function() {
    jQuery(\'.copy\').mouseover(function() {
        var txt = jQuery(this).attr("title");
		var url = jQuery(this).attr("href");
        clip = new ZeroClipboard.Client();
		clip.setHandCursor(true);
        clip.setText(txt);
        clip.glue(this);
        clip.addEventListener(\'complete\', function(client, text) {
			alert("Copied to clipboard! Paste where you want it!" );
			if (url!=undefined){							//this is for
				window.location=url;						//<a href links
			}												//to do it
        });
    });
});
</script>';
}
?>
