Add Fl_Scheme::plastic_color_average() method [#464]
This method can be used to set a more appropriate color average to
prevent "graying out" the box colors of the 'plastic' scheme.
Alternatively environment variable 'FLTK_PLASTIC_AVERAGE' can be used
to set the color average value. See docs for details.
Set color average to 45% in test/unittests demo program.
