    Bug: fix grl.fetch() parameter order in lua plugins
    
    The grl.fetch() functions expects the arguments in the order of 1) the
    url to connect to, 2) the net options, 3) the callback, and 4) the user
    data. Some of the plugins were switching 2) and 3). This caused an issue
    where the net options were ignored.
