Undo: implement rudimentary undo of dive-notes editing

Browse source 
Implement a first rudimentary dive-editing command. The main code
resides in a base class Command::Edit, which calls virtual functions
to read / set the fields and extract the field name.

Implement an example: editing of dive notes.

This dose not yet update the UI on undo / redo.
