Print: add experimental code for printing profiles

Browse source 
PrintLayout::printSixDives() goes trough all dives
and prints their profiles on full portrait pages.

This method is based on resizing the ProfileGraphicsView
widget, plotting each dive and then 'grabbing' it using
QPixmap::grabWidget().
