Make sure libraries/frameworks coming from W3C JS repo are whitelisted

[tripu]

Either warn editors when their JS files aren't coming from our JS repository, or force them to use those copies instead of uploading their own when they publish.

Ideas?

@plehegar (/cc @deniak): this, iiuc, means relaxing this rule to accept
also
always
any
files under https://www.w3.org/scripts/.

Is that acceptable?

[deniak]

I don't see any issues doing that. The only constraint is to make sure nothing is deleted under /scripts over time.

Actually, a feature for https://github.com/w3c/third-party-resources-checker/
