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.

We used to only keep sites with dives around. This changed when
implementing the dive site tab. The paste-dive code was written
using the old semantics and thus, when overwriting dive sites,
it deleted unused dive sites.
To make things consistent, remove that code. It would be very
weird when dive sites are deleted by pasting, but not by setting
a different dive site manually.
Bonus: no more dependencies on desktop-includes in the undo code.

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

Instead of using a sub-array, use a std::vector<>. This is
a necessary step in removing the MAX_CYLINDERS restriction.

Implement an undo command that overwrites the dive-computers and
cylinders of the current dive with a given dive. This will be used
when replanning a dive.

When pressing F2 in the dive list, the number can be edited.
Make this action undoable by implementing a EditNumber command.
This command is differs from the other undo commands, as not the
currently selected dives are changed. This means that the EditCommand
needs an alternative constructor taking a single dive. This constructor
was implemented in the base class so that all edit commands can now
be called with a single dive.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

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.

The edit-commands were called with a list of selected dives and
the original value. Move the creation of the list and extraction
of the original value into the edit-commmands.
This removes the "current is last" rule and allows for more
flexibility.
Since the depth- and duration editing applies only to the current
dive and not all selected dives, add a parameter to the edit-commands
controlling whether only the current or all selected dives are edited.

This was a bit different from the other editing commands:
1) Only the current dive is edited not all selected dives.
Therefore, create a function that turns the current dive
into a one-element list.
2) The profile has to be replot. Here, likewise, create a
function to do that.

The code follows the other edit-commands, but uses its own base
class, because it is distinctly different. Editing the tag field
does not simply mean setting the tag for all dives, but rather
adding and removing individual tags.
This class will be reused for editing of dive buddies and masters.
Modify the tag widget thus that it sends an editingFinished()
signal when it goes out of focus. The editingFinished() signal
was prevented by hooking into the return, enter and tab key-events.

This one is a bit more tricky. There are two modes: set dive site
and set newly created dive site. This is realized using an OO model
with derived classed. Quite convoluted - but it seems to work.
Moreover, editing a dive site is not simply setting a value,
but the list of dives in a dive site has to be kept up to date.
Finally, we have to inform the dive site list of the changed
number of dives. Therefore add a new signal diveSiteDivesChanged.
To send only one signal per dive site, hook into the undo() and
redo() functions and call the functions of the base class there.

Mostly trivial. Since now on editing the field is re-set, the

This one was trivially modelled after notes editing. Only difference:
the textChanged() signal was replaced by the editingFinished()

Add a new UndoCommand for dive mode editing. This one is a bit
special, as the mode is associated with a dive computer (DC),
not a dive. Thus the edit command has an additional parameter,
viz. the index of the DC.
This does not fit properly to the EditBase class, as this class
isn't aware of additional parameters and therefore this parameter
is not sent via signals. At the moment this doesn't matter. In
any case, the semantics of editing are weird and therefore let's
do the simple thing (derive from EditBase) and let's see what
the future brings.

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.
