PPTX: implement native handling of <a:clrScheme> children

This was already handled by converting them to raw colors at import
time. This commit imports the color scheme contents (the 12 colors) into
the doc model.

This is a dependency to export them back to PPTX and to be able to
update these colors on the UI by picking a different theme.
