    Fix directory-index-handling
    
    Previously, quark would properly check for the docindex-path, but not
    actually change the response-struct accordingly. I missed this during
    the restructurization of the code.
    
    Thanks to Quentin Rameau for spotting this issue! This commit is based
    on his patch.
