Currently they are showed as normal messages, log viewers should be able to distinguish normal messages and "/me"-like ones.
This is represented by TP_CHANNEL_TEXT_MESSAGE_TYPE_ACTION, the problem is that we don't expose the TpChannelTextMessageType out of TplEventText. I'll fix that while doing TplEvent refactoring, we simply need a public function to get this. Also the XML log-store already support it (see 'type' attribute of xml format).
Fixed in 0.2.0 (now 0.2.1). See TplTextEvent::message-type. /me messages are of type TP_CHANNEL_TEXT_MESSAGE_TYPE_ACTION.
