Feature Request: Allow different NoScript permissions per container

[Qsario]

I'd like for NoScript to integrate with the new Firefox containers (contextual identities) by allowing users to associate script permissions either with containers or make them global. This would enable permitting Google, Facebook, etc. script domains only when running in the relevant container, rather than having to temporarily permit and revoke permissions constantly to make use of the sites.
