Improve BPEL refactoring

Often times I find myself changing the names of variables, port types, partner links, etc. either in the Property sheet or directly on the editor canvas without thinking; what I really wanted to do was refactor the name change and have it propagate through to the WSDL or XSD where the element is defined. It would be simple enough to provide a change listener that prompts you with "Hey, I noticed you changed the name of this <thing> - did you intend to refactor instead?" possibly with a "Don't ask me again!" checkbox. The same functionality should be provided for the WSDL and XSD editor. This would go a long way to better integration within the tooling.
