[/trunk] Changeset 88 by mikael
* Switch to using hbuf, the new history buffer implementation.
* I've had to rewrite some parts of the interface, and I have removed
the frames for the roster and the chat window.
* The wrapping is not perfect, as the prefix is not yet treated separately...
* Seems to be a display problem when receiving UTF-8, too. :-(
