QDeclarativeTextInput sends delayed mouse events to input context

QDeclarativeTextInputPrivate::sendMouseEventToInputContext()
now forwards also the delayed press events (sent by
QDeclarativeFlickable) to Input context. In case of delayed
event QWidget pointer in QGraphicsSceneMouseEvent parameter
is null and QApplication::focusWidget() is used to obtain
QWidget pointer.
