dynamic query strings using token

Hi ,
I suggest this feature : to make a change to function path_redirect_init , to allow dynamic insert of params like , user name or any other created by modules.

the code need to be inserted in line number 49 of the selected version.

if(module_exists('token')){
    	$r->query = token_replace($r->query);
    }

I have tested it and it works very good for me.
