Notify suggester about accept/reject suggestion comment

[unho]

Suggesters must be notified comments on accepted suggestions, and most importantly, rejected suggestions. Without this the accept/reject suggestions feature now in place (#4629) is basically useless.

Whether that notification should happen by email, or using GitHub-like notifications in Pootle UI, or both, is something that needs agreement.

Related #5040.

i think the priority here is more notifying of accept/reject actions than just the comments

[unho]

Suggesters can benefit much more from comments on accept/reject, so IMHO that is the priority. But I don't see why both can't be achieved at the same time.

[unho]

This is now fixed.

Does reviewing's notifications by email work with the final release (2.8.2)?
Because I configured the email and tested it by (pootle sendtestemail) and it worked, but no email is sent after reviewings.

Hi all, same question as above. Did this feature ever make it into the latest 2.8.2 release? If not, is there a way to cherry-pick it? Thanks!
