profilewidget2: add resetZoom()

Browse source 
resetZoom() is now a new method that is called both
when 'printMode' is updated or when the dive is re-plotted.

Fixes a bug where zooming in on the profile and then
printing the dive has the profile at the wrong zoom level (makes
the profile look smaller).
