#2 Check for JList element count

[Stefan Roock]

It is not possible to check the element count of a
JList in the moment since the element count is not a
direct property of JList.

The element count can be computed via the model:
myList.getModel().getSize()

Possible solutions:
* provide special functions in the test language or "phantom
properties"
* extend test language for method call chains like
myList.model.size
* provide special handling for model and allow access to all
model methods directly at the widget, like myList.size - but
this may cause method name clashes (with size at Jlist this
actually is the case)
