Store zoomed plot in preferences

This patch makes the 'Zoomed Plot' a preference that can be stored and
retrieved, this way if the user sets the plot to be 'zoomed', this
information will persist even if they closed or opened subsurface again.

Also, added the 'Scale' button on the new profile, but didn't did the glue
code yet.
