Remove TreatNullAs=NullString for HTMLInputElement

Remove TreatNullAs=NullString for HTMLInputElement

http://whatwg.org/html#htmlinputelement
http://whatwg.org/html#HTMLInputElement-partial

The value attribute has [TreatNullAs=EmptyString] in the spec, so
leave it with [TreatNullAs=NullString] even though that doesn't
exactly match the spec, to be fixed in a later commit.

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

Firefox reflects autocomplete as the empty string, and doesn't support
dirName.

IE throws an exception for align/type, doesn't support dirName, and
doesn't reflect formAction as a URL.

Opera doesn't reflect formAction as a URL, and reflects min/max as the
empty string.

LGTM

This one looks slightly more scary. Lets sleep with our eyes open tonight.

Indeed, some regression somewhere is likely.
