Update of user manual
Several updates are implemented here.
1) Updates to the dive planner section, following excellent
suggestions from Rob.
2) Updates reflecting the date picker, including hitting ESC
to close the calendar.
3) The edit of device names.
4) Several small or typographic edits

There is quite a bit of work to do on images.
1) Please tell me when the date picker is finalised. About 6 images need
to be replaced for this one.
2) The Planner. I think four images. The planner layout is currently
under discussion so I do not want to
do it until the layout has been finalised.
Kind regards,
willem

+==== Changing the name of a dive computer
+
+It may be necessary to distinguish between different dive computers used to
+upload dive logs to _Subsurface_. For instance if one's partner's dive computer is the
+same make and model as one's own and dive logs are uploaded from both dive computers
+to the same _Subsurface_ computer, then
+one would perhaps like to call one dc "Annie's Suunto D4" and the other one
+"John's Suunto D4". Alternatively, perhaps a technical diver dives with two or more
+dive computers of the same model, the logs of both (or all) being uploaded.
+In this case it might be prudent to call one of them
+"Suunto D4 (1)" and another one "Suunto D4 (2)". This is easily done in _Subsurface_.
+On the *Main Menu*, select _Log -> Edit device names_. A dialog opens, indicating the
+current Model, ID and Nickname of the dive computers used for upload. Edit the Nickname
+field for the appropriate dive computer. After saving the Nickname, the dive logs
+show the nickname for that particular device instead of the model name,
+allowing easy identification of devices.
