OData Metadata file Code is not in line with model options Code conventions

[harmen-xb]

The Code of the OData Metadata file is 'ODATA_METADATA', but the model options naming conventions the Code is set to Mixed Case. So when applying the naving conventions to all objects the menu option to update a model disappears.

I think it's better to update the name convention for this file.

Note: This does require existing models to be update with the new Code,

Change the Code to be Mixed Case. When an existing model still has the uppercase Code it will automatically be updated in the next model update (since finding the metadata file is now case insensitive).
