Update the text pertaining to CCR and pSCR dive logs to include the
changes with respect to:
1) Colour of CCR setpoint graph and pSCR OC-equivalen pO2 graph.
2) Display of bailout information on dive logs.
3) Preferences tab allowing setting pertaining to the above.
This is the first of a few PRs with updates to the user manual
relating to CCR and pSCR dives.
Correct some typos.
