PPTX export: handle theme color of shape text with effects

Handle luminance modulation and offset (lighter and darker colors in
PowerPoint); not handling tinting/shading for now, as that seems to be
not used in DrawingML (only in WordprocessingML), and this code is for
shape text only at the moment.
