Bug 55827 [Contributions] Need to remove refs to Platform.getDebugOption from JFace
build I20040323 Standalone JFace applications are currently broken due to several refs to Platform.getDebugOption in JFace, which is only available if Eclipse is running. Should have static flags for the various debug options in JFace, and initialize them from the Workbench.

/**
 * This method allows subclasses of <code>ContributionManager</code> to prevent
 * certain items in the contributions list.  <code>ContributionManager</code>
 * will either block or allow an addition based on the result of this method
 * call.  This can be used to prevent duplication, for example.
 * @param itemToAdd The contribution item to be added; may be <code>null</code>.
 * @return <code>true</code> if the addition should be allowed; 
 * <code>false</code> otherwise.  The default implementation allows all items.
