Profile: support grayscale plotting

Browse source 
This patch adds the getColor() helper function to
ProfileGraphicsView and EventItem so that retrieving
a certain color can depend on a 'isGrayscale' flag.
This flag is private and only set by
ProfileGraphicsView::setPrintMode() at this point.
EventItem also now accepts 'grayscale' as a constructor
argument.

A couple of side modifications are:
- move setBackgroundBrush() to ProfileGraphicsView::plot()
- set the same pen color as brush color for the dot in the
'!' symbol inside EventItem::EventItem().

TODO: look for color issues when printing using the
custom grayscale table
