Show multiple gas pressures in the profile even if the dive isn't CCR

Browse source 
Now that the cylinder pressures are more generalized, we should show
them even for non-CCR dives if we have them.  The most notable example
would be having separate pressure transmitters for both cylinders in a
sidemount setup. The code no longer really depends on any CCR logic.

NOTE! This is still preparatory work, in that this is one part of
supporting multiple simulataneous cylinder pressures, but we are still
lacking in other departments (eg properly filling those fields in when a
dive computer exports multiple pressure sensors etc).
