    Reorder and extend glyph attributes

    Faint, invisible, struck and fast blink are added as glyph attributes.
    Since there's an edit here, let's take the opportunity to reorder them
    so that they correspond to the two's power of the corresponding escape
    code. (just for neatness, let's hope that property never gets used for
    anything.)
