Integration factory script fields

The Vulnerability Integration form contains fields that provide the logic to actually instantiate the object defined by the script include reference fields, integration script, and report processor.

When the script include is selected both fields are pre-populated with a no-argument constructor call. Often, this is sufficient, but there can be occasions where more logic is required to instantiate the script object.

The integrationProcessGr record is exposed to the factory script fields so process-specific information can be used, as needed.
