Streamline the initialization logic

The new initialize() function in QIviFeatureInterface is now called
by the QIviAbstractFeature after all signals are connected in the
connectToServiceObject() function.

The initialize() and initializeAttribute() functions have beeen removed
from all other interfaces and the default implementation is used.

QIviAbstractFeature now provides a new isInitialized() property, which
changes to true, once the backend has informed the feature about its
current state and the initializationDone() signal was send.
