Users with no editing ability on a review request should not see issue buttons on inline comments

Review Request #2419 — Created June 23, 2011 and submitted — Latest diff uploaded

Review Board
I noticed that after I'd created a review with some issues, when I went and viewed my comments in the diff viewer, the buttons for dropping / fixing the issues were visible to me, even though I was not the review requester.

This patch fixes that bug, as well as putting the issue status message in the inline comments.  Not sure how that one slipped by.
Manual testing.
