Important change in WebIDL (Was: [Bug 10640] Allow for non-nullable objects)

Hi,

The Web IDL spec has just integrated a change that introduces a fairly
big backward-incompatibility: up until now, the declaration
        interface Foo {
          attribute Bar myAttribute;
        }
implied that "null" was a valid value for myAttribute (since interface
objects were always nullable).

After the change described below, this is no longer the case, and
nullability needs to be made explicit, à la 
	interface Foo {
          attribute Bar? myAttribute;
        }

(this applies as well to method arguments and return types)

This like affects most of our APIs, and most certainly the Contacts API
(which I now note is lacking the nullability marker on attributes of the
Contact Interface)
