Proposed spec changes in need of review

All,

I have 10 outstanding PRs
<https://github.com/w3c/webcrypto/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aopen%20label%3A%22needs%20review%22%20-label%3A%22needs%20input%22>
that require review. Most are pretty simple. I'd really appreciate group
members taking a quick look and indicating whether the changes look good so
I can get them merged.
