Description
-------

Fixes the crash when trying to close the script editor.

When an user is closing the script editor, destroyed() signal of the class ScriptEditorWidget is called, the it will call CantorPart::scriptEditorClosed that will call CantorPart::showScriptEditor that will try to delete explicitly the initial caller (the ScriptEditorWidget), that was the cause of the crash.

Testing
-------

1. Run cantor
2. View -> Show Script Editor
3. Close Script Editor
4. Check that the check box from the "Show Script Editor" is in the unchecked state and the ScriptEditorWidget object has been destroyed successfully.


Thanks,

Minh Ngo
