Subject: [PATCH] Display CCR setpoint values on the po2 graph (V2)

This is version 2 of this patch.
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. By default the box is checked.
Most of Dirk's comments on the first version of this patch are
addressed here.

The problem of crazy uninitialised setpoint values for Poseidon dive logs
is corrected by Miika in a separate patch.

The graphics code needs careful check by someone familiar with Qt, please!
