5e29245e68 Refactoring: move undo commands to top level
In the future we might want to use undo-commands for mobile as
well (even if not implementing undo).

Therefore, move the undo-command source from desktop-widgets
to their own commands top-level folder.

7f4d9db962 Cleanup: move trip-related functions into own translation unit
These functions were spread out over dive.c and divelist.c.
Move them into their own file to make all this a bit less monolithic.

f51e402e04 Undo: only show warning message if dives were actually edited
The multiple-dives-edited message was shown even if the value was
not changed. Notably, when tab-flipping through the dive fields.

Therefore, changed the execute_edit() function to return zero
when no command was executed. For this, return a boolean from
the execute() function indicating whether the command was really
executed or trashed.

03d5e641e1 Undo: return number of changed dives from undo commands
To enable a "multiple dives edited" message, return the number
of edited dives from dive edit undo commands. Since there are
two kinds of these commands, viz. normal fields and tag fields,
and the former use templates, create a common base class that
can return the number of dives. Yes, the class hierarchy is
getting scarily deep! At least, this gives a tiny bit of
code-reuse.

c22fd9f4fd Dive sites: prepare for dive site ref-counting
Add a dive site table to each dive site to keep track of dives
that have been added to a dive site. Add two functions to add
dives to / remove dives from dive sites.

Since dive sites now contain a dive table, the order of includes
had to be changed: "divesite.h" now includes "dive.h" and not
vice-versa. This caused some include churn.

82af1b2377 Undo: make undo-system dive site-aware
As opposed to dive trips, dive sites were always directly added
to the global table, even on import. Instead, parse the divesites
into a distinct table and merge them on import.

Currently, this does not do any merging of dive sites, i.e. dive
sites are considered as either equal or different. Nevertheless,
merging of data should be rather easy to implement and simply
follow the code of the dive merging.

43c3885249 Undo: isolate undo-commands
This refactors the undo-commands (which are now only "commands").

- Move everything in namespace Command. This allows shortening of
  names without polluting the global namespace. Moreover, the prefix
  Command:: will immediately signal that the undo-machinery is
  invoked. This is more terse than UndoCommands::instance()->...
- Remove the Undo in front of the class-names. Creating an "UndoX"
  object to do "X" is paradoxical.
- Create a base class for all commands that defines the Qt-translation
  functions. Thus all translations end up in the "Command" context.
- Add a workToBeDone() function, which signals whether this should be
  added to the UndoStack. Thus the caller doesn't have to check itself
  whether this any work will be done. Note: Qt5.9 introduces "setObsolete"
  which does the same.
- Split into public and internal header files. In the public header
  file only export the function calls, thus hiding all implementation
  details from the caller.
- Split in different translation units: One for the stubs, one for
  the base classes and one for groups of commands. Currently, there
  is only one class of commands: divelist-commands.
- Move the undoStack from the MainWindow class into commands_base.cpp.
  If we want to implement MDI, this can easily be moved into an
  appropriate Document class.
