Subject: [PATCH] Give PanelSlider a right-click signal

Sliders only ever accepted the left button. Audio wants right-click as a
secondary action on the track, so emit rightClicked() for it and keep dragging
left-button-only: press and release both ignore anything else, so a right-click
can neither start a drag nor move the value.
