Display CCR setpoint values on the po2 graph

When a CCR dive is viewed and the toolbar button for PO2 is activated,
both the PO2 (green line) and the O2 setpoint (red line) are shown.
This allows evaluation of the PO2 in the CCR loop with respect to the
pre-configured O2 setpoint.

The setpoint graph can be disabled from the Preferences/Graphs tab
by checking the appropriate checkbox.
