Bug 1286027 - Display MozReview diff stats r=glob

Now that MozReview's ReviewRequestSummary API has diff stats (lines added
and removed), we can display that in BMO's MozReview table.

I also removed the commit ID and made the summary link to the diff, since
the former doesn't seem to be particularly useful.
