QtBase: Fix painting example arthur background color

Browse Source 
The arthur style set the background color to a bright color
and leave the foregroud color, for example for text, untouched.

If you are using a color theme with bright foregroundcolors on your
system this will result in unreadable text on push- and
radio-buttons.

The function drawControl is now reimplemented and the labels
with text are drawn with an appropriate color.
