Updated IdP to new spec.

Hello everyone,

As of yesterday (Nov 26th), the authentication endpoint at 
https://auth.fcns.eu will only accept WebIDs written using the new 
specs. The tests it offers include a particular test for the old vs new 
spec, so that users should have at least one way of being alerted of 
this change.

Also, the suite at http://webid.fcns.eu will now produce WebID profiles 
using the new spec. Unfortunately, I haven't yet got around to updating 
old profiles, so for testing purposes you might have to create a new one.

As it is, I'm not aware of any bugs so far, but please report them as 
soon as you find one!

Have a great weekend!

Andrei
