If things go as planned, then the length of the polygon is the same as the
number of rows in the model. Turns out when running Subsurface-mobile on
Android that simple truth doesn't seem to be correct. Most of the time
the polygon seems to have twice as many elements as the model. But a few
times I ended up in here with a polygon that had fewer elements than the
model. And then things crash.
This simply avoids the crash.

DiveCalculatedCeiling is the last class the references
MainWindow in the profile-widget stack.
In modelDataChanged() it looks for the information()
widget and sets a slot for the dateTimeChanged() signal that
information() emits.
To solve the issue we make DiveCalculatedCeiling recieve
a ProfileWidget2 reference and make ProfileWidget2 emit
the dateTimeChangedItems() signal.
ProfileWidget2 itself listens for the dateTimeChanged()
signal that information() emits and emits dateTimeChangedItems()
to notify any possible children/item listeners in the
ProfileWidget2::dateTimeChanged() slot.
The connection between ProfileWidget2 and information()
is set in MainWindow. This makes DiveCalculatedCeiling
unaware of MainWindow and which class originally emits
the dateTimeChanged() signal to ProfileWidget2.

Think delegation.
Tomaz, please take a look at this one, to double check
if i messed up.
also i have zero idea how the mobile app is setting these
connections, if it does so even.

The new preferences dialog still needs a bit of fine tuning
but should already work.

The reason for that is, even if profile widget is made with qpainter
and for that reason it should be a desktop widget, it's being used
on the mobile version because of a lack of QML plotting library that
is fast and reliable.
We discovered that it was faster just to encapsulate our Profile in
a QML class and call it directly.
