Allow weblink to have an embed view like any other object

Hi,

As of today, we can't put weblinks as embed and see the content inside them like any other object. The embed is only a sort of iframe object instead.

This is particularly painful when the only current workaround is to make the weblink content a full blown gigantic group and then copying the reference to the group object instead of simply adding the weblink with @NAME_OF_WEBLINK with a default embed view.

This change should not be hard to implement, and would definitely prove useful I'm sure.
