Issue description

The implementation of ScriptLanguageExtension::preferred_file_name_casing is not backward compatible and results in the error that the method is not implemented when opening the Create Script dialog.

I think it would be better for extension authors that new methods continue to take a reasonable default and not explicitly require implementation, especially if the method is implementing customizable behavior when there as a previous default behavior. This gives the freedom for extension authors to implement this when it seems reasonable or applicable.

Steps to reproduce

1. Implement custom script extension and language.
2. Cick new script to open the Create Script dialog
3. Error is reported in the output panel
