* <li>Recalculate the average time between two messages
* It should only calculate this time if a chatwindow is open (sure, it isn't
* perfect, because we could let a chatwindow open a whole day but that's at this * time the nicest way, maybe we could check the time between the two last messages
* and if it is greater than, say, 10 min, do as there where no previous message)
* So we do this when the chatwindow is open. We don't set m_isChatWindowOpen to true
* when a new chatwindow is open, but when a new message arrives. However, we set it
* to false when the chatwindow is closed (see StatisticsPlugin::slotViewClosed).
*
* Then it is only a question of some calculations.
*
* <li>Recalculate the average message length
*
* <li>Change last-talk datetime
