Link to now produces absolute urls...

We can now use absolute URLs around the site.

 We need to support different domains (e.g. for Identity).

 We no longer need most of the complexity of LinkedTo (it has not disappeared, it has just moved to Fastly following the domain switch).

If you have the site.url property set e.g. site.url=http://www.theguardian.com than links built by LinkTo will be absolute. If not they will be relative to the root of the site.

By default dev machines will use relative urls.
