Bugfix: show proper dive mode The dive mode shown in the top line on the display was strange. It could only show CCR and OC, and dive modes Apnea and Gauge where shown as OC. With this commit, the proper dive mode is shown. Notice that these strings/abbreviations where not localized, and are still not localized with this commit. The localized names from the corresponding menu lines are not really usable (as too long) to shown in the header. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
