Loading a pre-existing incident does not show up when "done" is not clicked

[sdanthin]

The ScriptBuilderFrame? is not updated when a new incident is added from the incident chooser palette of pre-existing incidents and the done button is clicked. When the ScriptBuilderFrame? is updated, the loaded incident appears. Minor fix. Could cause confusion.

Steps to re-create:

1. open a new script
2. navigate to Incidents > Load Incident
3. add incident from chooser
4. close window instead of clicking done
5. Observe there are no incidents in ScriptBuilderFrame?
6. create new incident
7. observe there are now both of the created incidents in the frame.

Suggested fix:
make close button work same behavior as the done button.

Fixed in r191. Could change implementation to have an "apply" button, a "done" button and a "cancel" button to prevent accidental unwanted additions to the main script.
