Re: [dom] Change DOMTokenList's add() return value. (#114)

Hold on. So in https://github.com/whatwg/dom/pull/103#commitcomment-14496980 it is pointed out that it's likely not going to be Web-compatible to reject invalid values for `<a>.relList.add()`. If we want this for `<a>` as well, maybe we should revert the rejecting invalid values, and enable it for `<a>` now. (And `<area>`?)
