I would actually advise against it. I would much prefer if it's done in
the core, and the UI made aware not to do anything when conv->ui_data is
NULL. I think this would also make managing hidden conversations (from
the 'Hide Conversations when ...' option) easier, especially for
plugins that deal with PidginConversation.

I think a 'purple_conversation_unset_ui_' (which could call
conv_uiops->destroy_conversation, possibly) and a
'purple_conversation_reset_ui' (which will probably use up one of the
reserves from the conv_uiops bench) would be good.

This will also probably require keeping a list of messages in the
conversations (with the appropriate flags, timestamps etc.), which, I
don't think would be an entirely bad idea.
