[Willem Ferguson]

     User manual updates (part 3 of 3)
     
     This patch updates several areas of the manual:
     1) The import from dive computer using the new UI panel.
     2) The section dealing with exports
     3) Many other small changes.

Because of the size of many included images, I sent the original patch only to Dirk.

I send this for the benefit of our translators of the user-manual.

As far as I am immediately aware these are all the changes for V4.4. If I did
not take any new developments into account, I would appreciate it immensely if
you would let me know.
Kind regards,
willem
