Wildcard exclude fix

Sorry for not commiting a patch, but my FCKeditor is currently not standard.
This is a simple fix to make the exclude function simpler and work better.
This allows exlude filters like */add/* or node/*_issue etc.

In my code this starts at line 494 to the end of the file.
I am including the original code - commented out.

//	$Number_of_excludes = count($paths_excluded_array)+1;
	// check each array item to see if it matches an excluded path
//	for($i=0; $i<$Number_of_excludes; $i++){
//		$paths_excluded_array[$i] = rtrim($paths_excluded_array[$i]);
		
#		// IF WILDCARD in excluded path
#		if(strpos( $paths_excluded_array[$i] , '*' )){
#			//remove /* frpm excluded_path
#			$excluded_path = substr($paths_excluded_array[$i], 0, -2);
#
#			// see if the page path contains the excluded path
#			if(substr_count ( $page_path, $excluded_path)){
#				$path_match = 0;
#				break;
#			}
#		//IF no wildcard check to see if Page path = excluded path
#		}else{
#			if($paths_excluded_array[$i] == $page_path){
#				$path_match = 0;
#				break;
#			}
#		}
// by regx - Wow, lets just use a regx instead!
foreach($paths_excluded_array as $expath){
	$expath = preg_replace('/[^a-zA-Z0-9*]/','\\/',$expath);
	$expath = preg_replace('/\*/','.*',$expath);
	//print "$expath<br/>"; # for debugging
	if (preg_match("/$expath/",$page_path)){
		$path_match = 0;
		break;
	}
}
	return($path_match);
}
