-/* Concept Ideas
-* Probably makes sense to have ChatLineData be the AbstractUiMsg instead, if it turns out that creating ChatLineData
-is the expensive part... In that case, we could have a QHash<MsgId, ChatLineData*> in the Client, and ChatLine just
-gets a data pointer. This would allow us to share most data between AbstractUiMsgs, and ChatLines themselves could
-be pretty cheap - that'd be a clean solution for having a monitor buffer, highlight buffer etcpp.
