Also display other SE-site links as linked-questions

If you link to a question on the same site it appears in a table on the right hand side:

Linked Question Table

How ever if you link to a question outside of the site (even within the SE Network) it does not.

There is a natural overlap with some sites and it would be useful to be able to reference other sites, for instance in this question about the age of the universe might link to a question on Physics.SE.
