GDPR enhancement: No CDN

[Sam_uk]

It seems that Ghost uses a bunch of CDN stuff which makes GDPR compliance harder.

If I make the changes outlined in the link above to run those files locally, would you accept a pull request to the Ghost Cloudron package & offer the 'local only' as the default Ghost app?

@Sam_uk seems to have extensive code changes and also how the app is built. I fear this will not be maintainable in the long run. Do you know why the upstream project does not just rely on local assets?
