Compliance edits per CfOs on 219 and 235

(No call tomorrow, btw, sorry that I didn't check that with our chairs sooner. Next call to be announced.)

I've made the edits to implement the CfO results on issues 219 and 235: prohibiting use of data collected in a different context and removing auditability requirement respectively. On 219, I've tried to implement the Option B (with lesser objection) but using the current language ("party to a given user action", etc.). I would welcome group review to make sure I've made these changes correctly.

If you want to review more Compliance changes I've made, the list of Pending Review issues on this Tracker would be relevant:
  https://www.w3.org/2011/tracking-protection/track/products/5 <https://www.w3.org/2011/tracking-protection/track/products/5>
while I'm not sure that's actually exhaustively up to date on what we have completed, I do think all the Pending Review issues there can be closed if we're satisfied that I've implemented our text or addressed concerns adequately.

Thanks,
Nick
