Issue description
This is about being able to associate a dynamic graphic component to a running node.

We propose to create an API and hooks to easily plug any Swing GUI component displayed while the node is running. The following features should be considered:
  • ability to enable/disable the screen saver
  • ability to run it in windowed mode or full screen
  • provide a hook for receiving NodeLifeCycleListener events
  • provide a hook for receiving task execution events
  • provide a simple interface as entry point for custom implementations
  • provide a default, personalizable screen saver implementation (for instance using images/logos whose location is configurable)

Committed a first implementation in SVN trunk revision 2909, based on the old screen saver code we had in JPPF v1.x (!). What remains to do:
  • add a hook to receive events from individual tasks (only NodeLifeCycleListener events are supported in this implementation)
  • support for multiple screens in full screen mode
  • documentation
