Automatic Validator for correct attribution of art assets

[ahbnr]

We collect attribution information for all external art in SynergyQuest/Assets/Resources/ExternalArtCredits.yaml. This information is automatically displayed by the game in the "Credits" menu.

Since it is easy to forget to insert an entry when adding new art to the game, the build system of the game should automatically validate that all art is properly credited.

Hence we want an automatic validator for this which...

• Is callable from the editor menu
• lists paths to all art files not properly attributed
• is automatically executed by CI and build dialogs and stops the build if art files are found which have not been given proper credit
