    Rename REQ_MOD to REQ_IF_MODIFIED_SINCE
    
    The named constants for header fields of the response struct all
    pretty much matched the actual header name, which I think improves
    readability for everyone familiar with the HTTP-spec.
    
    The request header fields named constants followed the rule, except
    the "If-Modified-Since"-header, which is addressed in this commit.
