[PATCH] Add importing of working pressure from divelogs.de

[Miika Turkia]

We were missing the import of cylinders' working pressure when syncing
with divelogs.de. This piece of information is required for proper unit
conversions when user uses imperial units for displaying the
dive information. (Both Subsurface and divelogs.de use metric
internally, or at least the export from divelogs.de is in metric.)

See #907
