ircutils.FormatParser: Make getInt only get integers that are valid colors

If a colored message were wrapped just right (e.g., a colored number ending
the chunk), FormatParser would gobble up the color format code and the number
in the message, causing a KeyError when trying to look up the color in
mircColors.
