Improve the references to the local fonts
    
    src:url() only accepts format(), not type().

    This should improve rendering of fonts via webserver.
    Fixing this uncovered another issue: if src:url is correctly specified,
    Firefox attempts to load the fonts from that url, rather than look for
    the local font first. To achieve the correct lookup order,
    src:local() should be defined before the url.
    Firefox then loads from the first found location.
