Feature request: more complete logging

[GoogleCodeExporter]

Subj. Complete includes at least all the events that are displayed in most
jabber clients. Or, maybe, even more.
I already hacked in minimal join/leave logging for myself (can publish the
patch). But I also find it necessary to add quit message to the logs and
add renames logging.
Filtering out 'replaced by new connection' leave + next join could be
useful as well.
Both quit message and, therefore, filtering are impossible with my current
implementation.
