When creating the context menu, a special menu is created for
the dive computer name.
This was checked in a loop, that set a flag and exited early.
This can all be simplified by moving the loop into its own
function. No more flag, less indentation. Overall better.

When creating the context menu on the profile, the code has
to check whether the context menu is activated on the
dive computer name to show a special menu (delete / split
dive computer).
This was done by setting a special property on the item
and then checking for that property on the item that
the menu is invoked on or its parents.
The reason the code didn't simply check the pointer was
probably that DiveTextItem uses multiple inheritance:
It derives from QObject and QGraphicsItem. It has to derive
from QObject first, because (the ridiculously broken) MOC
needs it that way. The object added to the scene is a
QGraphicsItem. Thus, we get a pointer _into_ the DiveTextItem
object.
However, that's all completely unnecessary. We can simply
compare the pointers, as the compiler will understand that
QGraphicsItem is only the second base class of DiveTextItem.
Magic!
Let's remove the cruft and simply compare the pointers.

When printing, the animation speed was set to 0 by the
caller and later reset to the original value. Instead of
modifying global state, set it internally (in the profile-code)
to zero when in print mode.
This is another small step in making the printing independent
from the shown profile.

When showing the "empty-state", the profile toolbar was
disabled. This was done via a "reverse" signal from the
profile to the MainWindow. Instead control the toolbar
in the MainWindow directly. Break out the plot-dive
functionality into a member function and there test
whether a dive is shown or not.
The signal makes no sense in the context of mobile

When switching to the "plan" or "add" (which should rather be
called "edit", by the way) mode of the profile, the "shortcuts"
for copy&paste, undo&redo, etc. are disabled. When switching
to "profile" mode, they are reenabled.
This was done in a most convoluted way:
- The MainWindow calls the set*State() function of the profile.
- The Profile emits [disable|enable]Shortcuts() signals.
- The MainWindow catches these signals and does the enabling
or disabling.
Not only is this very hard to reason about, it is also in
contradiction to the profile being part of the display layer.
Moreover, in editCurrentDive() the MainWindow disabled the
shortcuts itself, so this was all redundant.
For the sake of sanity, let's just move this logic to the
MainWindow, unslotify the [disable|enable]Shortcuts() functions
and make them private.

In planner or profile-edit mode, the plotDive() function takes
the current plan and turns it into a dive profile. Not only
is this a layering violation (the display layer modifying the
dive), it is also fundamentally flawed. The control-flow is
out of control, if you wish. There are numerous reasons why
the profile needs to be replot, many of which do not need
a recalculated dive profile.
Move the code that updates the dive-profile to the
DivePlannerPointsModel. Thus, the profile recalculations
and replots can be pooled. This will break the planner, since
there now might be missing calls to the profile recalculation.
But it already has some positive effects: when removing
multiple points, the profile is only recalculated once.
This will need much more work, but it is a start.

The DivePlannerPointsModel::addStop() function is called by
the profile to add a planner-stop. It is also used internally
to create profiles.
If we ever want to include this in the undo system, we have
to split these into to versions. One will ultimately place
an undo command and update the profile, the other one doesn't.
For now, this makes the external interface simpler, as some
parameters are redundant.

The dive handlers are only updated by signals. This means that
switching into edit-mode has to be done in steps:
1) initialize the DivePointsPlannerModel
2) switch profile mode
3) load dive into DivePointsPlannerModel
2) and 3) cannot be exchanged, or the dive handlers are not
initialized.
To avoid this sandwitching of profile- and model-initialization,
populate the dive handlers when switching the profile mode.
Thus, the profile can be switched into edit/plan mode when
the DivePointsPlannerModel is fully initialized.
This will be important in upcoming commits, when the initialization
of the dive is moved from the profile to the DivePointsPlannerModel.

The DivePlannerPointsModel::createTemporaryPlan() function had
two distinct and independent parts:
1) create the data points.
2) create the dive sample and calculate variations.
The second part was only exectuted if the recalc flag was set.
Out of the two callers, one was explicitly disabling and setting
the recalc flag to avoid the second part.
The much more logical thing is to simply split the function in
two and only call the first part.
To avoid any functional change, the second caller (the profile)
still tests for the recalc flag. However, if it shouldn't replot
a new plan, why calculate it in the first place!? And why does
the display function change the plan at all? This appears all
very ill-thought out and should be changed in due course.

When moving "dive handlers" with the cursor keys, the
profile was replot twice:
- First the recalculation of the planner model was suspended.
- The "stop" was moved.
- This led to a replot by a signal from the planner model.
However, the old profile was shown, since the recalculation
was suspended.
- The recalculation was reenabled.
- The profile war replot, resulting now in the correct profile.
A classical case of bit rot.
Instead, don't suspend calculation in the first place. This
shows the correct profile on the first replot and the second
replot can be removed.

The ItemPos structure describes the position of various chart
elements on the scene. It had two problems:
- The identifiers were starting with an underscore followed
by a capital letter. This is reserved to the compiler.
- The global object was initialized in the ProfileWidget's
constructor. This means that if there are multiple
ProfileWidgets, the structure is reinitialized even though
it is constant.
Remove the underscores (what was the point anyway?) and
initialize the structure in its own constructor. Moreover,
make the object const to drive the point home.
If this ever needs to be variable, each ProfileWidget
should get its own copy of the object.

So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()

There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).
The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues
Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.

When reordering the points, the DivePlannerPointsModel would
not emit the appropriate move signals, but simply a data-changed
signal over all elements. This obviously violates Qt's
model/view API, though it is probably harmless. Let's do
the right thing so that the frontend knows that the selected
item changed place.
Also, emit dataChanged only on the actually changed element,
not all elements.

The ProfileWidget2 slots, which reacted to model changes were
broken. They did not add / remove items at the changed positions,
but arbitrarily at the end. Moreover, they assumed that only
a single item was added / removed and thus violated the model/view
API.
This worked because the handles are completely reset after each
operation and the model only ever touched single items.
Nevertheless, this has to be fixed if we ever want finer grained
undo.

The profile item that shows the ceilings adds a warning event
if the ceiling is violated. This is very unfortunate.
Improve this situation by adding the event up to the function

be - the display layer should not modify the dive that it
displays.
To make this clear, add a comment that details that this
