Title: [review] 2961 pluggable previews

This pull request includes a new plugin interface for previews. Extensions can be a preview for a resource and will be displayed in an iframe.

Points to discuss:
* Is the interface simple enough and also powerful?
* Is it okay that no exceptions occur if there is more than one preview for a resource?
* Does the same origin check make sense? Can it be improved?
* Should the previews be exported to non-core extensions? All of them? Only one?

Pending:
* Docs
