[Plugin: Processing JS] Message for IE users

As processing.js doesn’t work on Internet Explorer (despite some simple examples on IE9) I give a message to IE users. The easiest way (but probably not the most elegant) consists in two modifications of the plugin:

1. Deactivate processing.js reference in header because of erros it produces on IE changing line 32 of processing-js.php:

if (isset($_SERVER['HTTP_USER_AGENT']) && (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') == false)) {
	wp_enqueue_script('processing-js', plugin_dir_url(__FILE__) . 'js/processing-1.3.6.min.js');
}

2. Show error message instead of Canvas adding code to line 8 of js/init.js and putting the rest of the code inside else statement:

if (jQuery.browser.msie) {
	jQuery(document).ready(function($){
		var script = jQuery("script[type*=processing]").get(0);
		jQuery(script).after("<p>IE doesn't support canvas, please use Firefox or Chrome.</p>");
	});
}
else {
	//original javascript code of init.js
}
