Selected Class Traversable Fields

[mfansler]

When a class UML object is selected, the fields in the class should be traversable via the Tab key and the fields in the Properties Pane should no longer be on the traversable list. That is hitting Tab repeatedly should cycle through the fields in the class and not jump to the Properties Pane. If a field in the Properties Pane has focus, then repeatedly hitting tab should cycle through the fields in the properties pane and not send focus back to the class UML object.

Once the text becomes editable, it is now possible to tab through the textFields of the UML object but the text fields on the properties pane are still traversable.
