    Add documentation for the "-u" and "-U" options.

    src/oping.h: Don't use the ncurses internal _nc_unicode_locale() function.
    
    The "-u" and "-U" options are now handled in a single variable so that the
    last option "wins".

    add commandline flag for forcing or disabling unicode
    
    note that "forcing" may not work: ncurses still expects your locale to
    be correct, so maybe the force flag should also explicitely set a utf8
    locale?

    move unicode detection to a separate function
    
    this will ease transition to a commandline option override

    autodetect unicode, and fallback to ACS scancodes on failure
    
    this is fairly ugly - we use a hidden ncurses function to detect
    unicode (but at least we don't reimplement it), then we mess around
    with the character arrays to display the rights symbols
    
    i am not sure i like this, but i prefer to braindump than to stall, so
    let's move forward.

commit ae1a4da882a8d213bb6a81d373bccaaa31245e94

    Refactor the graph printing into its own function.
    
    This makes it much easier and cleaner to add a second, non-Unicode
    implementation and possibly even a non-color version.
