Annotation View: Performance improvements

With large models, the annotation view can slow down the GUI of AF3 since it updates itself on model changes.

The following improvements are suggested:

• Update view only when it is raised. This will hide the performance problems in the default settings for the “Modelling” perspective
• Switch to virtual tableviewer (SWT.VIRTUAL) that renders only the visible part of the table
