Schema Router's ignore_database option's documentation should be clarified

I've been told that the Schema Router's ignore_database option can accept a comma-separated list of fully qualified table names, in addition to database names. However, the documentation only mentions that it accepts database names.

If it can really accept fully qualified table names as well, then I think the documentation should say so.

It should probably also have an example.
