Add more consistency to docking panels and widgets

* Dock panels shouldn't have any frame border or anything like that.
* They should have an external margin of 3 pixels at their border,
  but then no further margins on the layouts (like sub-controls for
  the pipeline state views.
* Toolbars should be Raised & Panel frames. Later we'll replace them
  with actual QToolBars to better customise the painting.
