 Replaces `$app` with `Processing.app`, new `library_loader` (_but latter change should be transparent_).
 Uses a simplified `control_panel` interface, ie use `c.title('PanelTitle')` instead of `c.title = 'PanelTitle'`, the old examples still work with the the latest version of JRubyArt, but these examples require the latest version.
