Re: [webcomponents] Disallow attachShadow(...) for some elements. (#110)

I've updated the spec, with a warning -"The list is possible to change", with a link to this issue.
https://github.com/w3c/webcomponents/commit/ada4804e979685eb00ee00274a13b395e210245c

@annevk , yeah, I've added some elements to the white list.

To be honest, I can not explain the rationale for this list fully yet. Please consider this commit just as *the first draft*.
