Changed implementation of ToolkitDelegate isModalExclusionTypeSupported and isModalityTypeSupported, which changed in JDK 1.6.0 update 38.
Correct modal type checking was implemented in JDK-2181173 - isModalityTypeSupported is not handled correctly
Fixed WindowInterceptor test to deal with localization in Swing UI labels.
If Locale is no en_US test will fail due to different label. Bug in JDK7 hides this bug.
Refactoring: moved method to superclass.
