I have merged the two branches, apparently. Good thing is, it still
compiles and functions properly.

Perhaps we should also cosider imposing a limit on the history length.
Whether to have this limit in the UI or in the core, I am unsure.

We probably want to use a new icon in the buddy list to indicate that a
conversation is hidden (especially if there's new message in it). Will
the real Hylke Bons please stand up?

I do not really care either way. But we probably should emit
'conversation-hiding' signal just before the UI for a conversation is
unset, and 'conversation-displayed' just after the UI is reset. Plugins
may want to do things on either of these events. I think these signals
should be in the UI, and not in the core. This time, will some of
the real crazy patch writers please stand up?  ;)
