sidebar: Simplify the look of the toolboxes.

Get rid of the background (that is not based on the theme the user uses, so
will not play good with system integration), and just draw a shadow frame
around the toolbar buttons.

[We cannot get rid of that for good, the controls then look 'lost in space'
;-)]
