Shouldn't show a toast popup for your own message in MUC
Spark shows toasts popups (if they are enabled) for your own messages sent to MUC, which is superfluous.
Created a separate ticket for the Roar issues as it is not related to toast one (which was there for a long time)
This happens on my main machine also, but only with the new rooms.
On my testing virtual machines (WinXP, Win7) it also starts to show Roar popups after your first message in the MUC. This is not happening on my main machine (Win7 64-bit) though.
