Subject: [PATCH] Issue 179 scrolling continues unexpectedly

added a check to AbstractSlider._onThumbMouseMove() whether the main mouse button
is still pressed; if that is not the case then the scrolling operation is stopped.
for this, the DOM event must be checked because MouseEvent.isLeftButtonPressed()
does not work for mousemove.
