Remove TreatNullAs=NullString for HTMLObjectElement

Remove TreatNullAs=NullString for HTMLObjectElement

http://whatwg.org/html#htmlobjectelement
http://whatwg.org/html#HTMLObjectElement-partial

Make the codebase attribute reflect as a URL, as per spec.

The border attribute has [TreatNullAs=EmptyString] in the spec.

The tests for the updated properties pass in Firefox Nightly, IE11
Release Preview and Opera 12.16, with these exceptions:

Firefox reflect code as a URL.

IE throws an exception for align, doesn't reflect codeBase as a URL,
and reflects width/height as the empty string.
