NewFileWizard for BPEL should add service and binding to WSDL artifacts

The New BPEL Process File wizard should add the <service> and <binding> elements to the generated WSDL.

A new wizard page needs to be built which allows the user to enter:
1. the service name (default is same as BPEL Process Name)
2. port name (default is same as service name + "Port")
3. service address (default is http://localhost:8080/<service_name>)
4. binding protocol (SOAP or HTTP)

The goal is to have the New File Wizard build a complete BPEL process and WSDL which can immediately be deployed to and run with the riftsaw (ODE) runtime.
