Prepare for PSCR calculations

Browse source 
Calculations for passive semi-closed rebreathers are pretty much like OC
except the pO2 is lower bey a certain (SAC dependent) factor. This patch
introduces the corresponding calculations in case dctype == PSCR which is
so far never set and there is currently no UI for these calculations. As
pO2 is SAC dependent it takes a certain attempt at getting it and drops to
defaults from the prefs otherwise.

As there is no UI at this point and I also don't have any dives, this has
not received much testing, yet, but it compiles. At least.
