Show altitude corresponding to surface pressure
In the information tab, presenting atmospheric pressure is a bit
unintuitive because the diver cannot easily relate that to altitude.
For the Atm. Pressure widget in the Information tab this code does:
If the atmospheric pressure for a dive exists and the user selects
the 'm' or 'ft' option from the combobox, then the estimated altitude
is shown in the text box.
