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.) Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
