SAGE Knowledge translator (new)

Sample URL:

Because of the way proxy detection works, the target regexp (where possible) should only match an unproxied host. (e.g. `http://knowledge.sagepub.com/...` is unproxied, but `http://knowledge.sagepub.com.some.library.proxy.edu/...` is the proxied URL), so this needs to end with a `/` Sorry for not catching that earlier.
