Fixed an NPE in DefaultPropertySources when there are no platforms (shouldn't happen).
More detailed logging when a JDK is chosen which is not of the requested version in DefaultPropertySources.
Using surefire 2.16.
Added IOTabMaintainer.
Removed some unused code from GradleTasks.
Added netbeans.run.params.ide to pom.xml because NetBeans complained when debugging.
Using IOTabMaintainer instead of InputOutputManager. This will allow later to add buttons the the left side of the output tab (such as re-run).
