Started the code for the Profile Plotting

This small patch adds a new class - ProfileGraphicsView
it's a QGraphicsView based class that will holds all
graphics-items for the plotting.

The setup is simple, just call ui->ListView->plot( dive )  ( that's
already a ProfileGraphicsView and magic will happen.

Since Im using a QGraphicsView , the size of the canvas doesn't
matter and I'm fixing it at 0,0,100,100. when a resize is done,
the resizeEvent will be called, fitting the scene's rectangle on
the view.
