[1673] Detect illegal inter model references in validation rule
This replaces the "ResourceSetListenerForInterModelInconsistencyDetection" with a new live validation rule I_39. The preference "Prevent on the fly inter-model dependency violation" from the Model tab has been removed. Change-Id: I1f7fb096f589f9dcda346363a390b7b30461c0bb Signed-off-by: Felix Dorner <felix.dorner@gmail.com>
