PDI-9462 - Fixing menus on SWT elements
PDI-4420 : Xul step/job entry dialogs (Hadoop uses Xul) need to persist
their window sizes (allowing SwtDialog to be subclassed)
removing the hardcoded swt.jar reference, loading with Ivy now
BISERVER-8671 - GwtToolbar respect the "visible" attribute when defined in a XUL file, defaulted PUC toolbar to not visible, added an overlay to default plugin.xml config to turn on the toolbar for the "Opened" perspective
