 * Helper class to parse IRC color/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)
