Untangle DiveCalculatedCeiling from MainWindow

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.
