Print: pass grayscale flag to setPrintMode()

We pass the value of 'color_selected' stored in the
print options to ProfileGraphicsView::setPrintMode().
This way the profile can be printed in grayscale
internally instead of converting a QPixmap to
grayscale.

There are a couple of questions here:
1) Are all the 'if/then' checks for all individual
colors faster than the direct QPixmap/QImage grayscale
coversation.
2) The direct grayscale conversation does not give
control of individual colors, but can it look actually
better?
