core: XMLUI notifications coming from backend are handled:
when a notification from backend is coming, it's added to a notification icon (on the right for important notifications which need user action, while left icon is used for notes).
If user click on the notification icon, the XMLUI replace the main widget with a rise animation. When action is finished, ui is closed with a fall out animation.
