tdf#148501 color shades only for filled PolyPolygons

For shading parts of a shape not of Type 'ooxml-*', ColorData is used,
introduced about 2005. For 'mso_spt*' shapes they are set directly,
for others they are encoded as 'col-********' into the Type value.
During OOo time two changes were made, resulting in the bugs, that
colors are assigned to wrong segments and that shadings are too dark.
More details are in the bug report.

With this patch the colors are assigned to the correct segments again.
The too dark colors are visible in our preset shapes 'Octagon Bevel'.
The shape 'Diamond Bevel' with corrected color assignment is also
affected. Both need new ColorData. Since it is important for
Libreoffice to have good compatibility with OOXML, I have decided to
use only the four shading values available in OOXML. In the long run,
these shapes should be replaced by ones that contain the shading
information inside the <enhanced-path> element.
