notes first draft: Implementation of XMLUI notes. There is a new header on top of root widget which display notifications, and notes are shown for a couple of seconds. A blue Cagou head appear when there are notes, and user can display 10 last when clicking on it. This header will probably not be present on platforms such as Android, because there is already a system-wide notifications handler which can be used instead (saving visual space).
