Setting a Notification's urgency

[Christoph Feck]

Hi,

according to a comment in a bug report[1], applications can specify an 
"urgency" property with notifications, with the intention that 
anything non-critical will automatically be removed after some time 
idling in the notifications list.

Is this API still available with the QML notifications rewrite, and if 
yes, how do applications set this urgency? For the reference, I would 
like to resolve kdialog bug 328099 by allowing the user to optionally 
specify such an urgency attribute. The code in kdialog uses a D-Bus 
call to create the notification.

Thanks,
Christoph Feck (kdepepo)
