Bug 576521 - Avoid UI freezes due to slow Debug view

Only proceed maximum 100 model changes of the
Debug view in one batch and then give other
UI tasks a chance to proceed in between.

This should avoid long UI freezes while updating
the JFace tree in case debuggee application generates
many model changes that need to be processed in the Debug view
