This PR removes all remaining uses of the obsolete AppContext from Swing classes. - Timer : just some comments - SwingUtilities - now unused utility methods - SwingWorker - now a single ExecutorService and revert to clean up via a shutdown hook - RepaintManager - display changes no longer need to be scheduled for each AppContext - UIManager - obsolete checking for swing defaults set from an AppContext is removed - this looks to me to have been obsolete ever since plugin was removed.
