D6392: [Panel Config] Scrolling over size button increments size by 1 and shows current thickness

REVISION SUMMARY
  The current thickness is also shown when dragging as well.
  Closing the ruler thing and reopening will recreate the component, so the Width/Height text will reset.
  
  I could use `Qt.binding(funtion(){ return panel.thickness })` but I don't think the panel will procedurally change with the panel's config open.

  Here's a demo: https://streamable.com/m2o7c
  
  Not intended:
  Moving the panel's screen edge triggered the `panel.onThicknessChanged`

  The best way to fix that is probably setting `button.text = panel.thickness` in the mousewheel event and in every case in the "drag" onPositionChanged event. Unless someone else can think of something better.
