Remove the close() method and closed attribute. Remove all the calls to
close(). (Save one bool per XmlNode, yay, and save a few ifs and some
useless function calls. At best it should be unnoticeably faster and lighter
and save a few keystrokes in the future)
The generated XML is very verbose because each IRC formatting tag makes us
close a <span/> element and reopen it with the new style applied. However,
this works quite well and is easy to implement.
