Show correct gas density in CCR mode

Browse source 
When collecting the data for the infobox, we have
already computed the current partial pressures of the
breathing gas taking into accoutn the divemode. Use
those rather than fractions (which for CCR mode are
those of diluent) to compute the gas density.
