PreferencesChanged -> settingsChanged.

We used both preferencesChanged and settingsChanged in different
methods and classes to mean the same thing, this adds consistency.

Move settings of the Ruler to the Ruler.

As with any other graphics object, the settings for the ruler
should be managed by the ruler, clearing up the Profile logic
and making the code easier to read.

Source and dest are created on the constructor, no need to check for them.

The code checked if dest and source existed before trying to call an
method on them, but dest and source are created on the constructor,
and thus, the if is dummy.

Temporary Tab Widget for the planner and the Profile View.

This is a temporary measure to help me port the planner to
the new profile. it will be removed when I finish the port,
but it makes the software still usable, so there's no worris.

Enable editing the 'Add dive' from the new profile.

This is highly broken in many ways - but it's the right first step.
I ported two of the most important methods from the old profile and now if
you are in add dive mode, double clicking on the new profile will
correctly add a handler on the planned dive. To see and move the handler
around, however, you need to activate the old planner.

Next step: add the handlers on the new profile.

Back to profile or empty state when finishing addition.

This patch adds a signal to MainTab, that should be removed from there
when we finish the rework on the edit part, to go to the edit classes,
but in the meantime, let's keep it there.

The signal is connected to the ProfileWidget in a way that the end of the
edit will also trigger the profile to go back to ProfileState (show the
dive, if there's any) or empty Profile (if there's none).
