Adjust ADT to new ITestRunListener changes.

This fixes ADT so it compiles against the ITestRunListener changes made
to support new JUnit4 states. It does not change ADT to truly support junit4:
eg use the junit4.runtime plugin, pass assumptionfailure and ignored test
states back to eclipse UI, etc
