parentcolor: allow "no-" for negating attributes (diff)

color: support "italic" attribute
We already support bold, underline, and similar attributes. Let's add italic to the mix. According to the Wikipedia page on ANSI colors, this attribute is "not widely supported", but it does seem to work on my xterm. We don't have to bump the maximum color size because we were already over-allocating it (but we do adjust the comment appropriately).
