QT GUI Control Widgets

Every QT GUI control widget in one flowgraph. The Numeric Entry retunes the tone and the Dial rides its level; the rest publish their state as messages, which the console pane prints. Each state control announces itself once when the flowgraph starts, so what the widgets show and what the graph believes agree before anything is touched.
