* Prepared CanvasFlag (and thus ChanvasProgramChange) to be able to receive Scroll wheel events

* made changes in editor_canvas_events.cc to forward events to CanvasFlag (against pauls advice), but IMHO it doesnt add complexity to it since it only adds a few trivial lines which do the same which has already been done for CanvasNote and thus shouldnt complicate the merge in any way
