// Helper class to parse IRC colour/style codes and convert them to
// richtext. The parser maintains an internal stack of the styles
// applied because the IRC message could contain sequences as
// (bold)Hello (red)World(endbold)! (blue)blue text
// which needs to be converted to
// <b>Hello </b><font color="red"><b>World</b>! </font><font color="blue">blue text</font>
// to get correctly nested tags. (malte)
