Automate the NodeUpdated notifications

Now, each time a signal known to be the notification of a property
change is emitted, we notify the observers automatically. Properties
for which no NOTIFY has been provided are ignored.

This change also allowed to drop quite some redundant code in QNode
subclasses.
