Issue 2971: make new_patchset more granular and flexible to reduce email
Status:  New
Owner: ----
Reported by rsp...@google.com, Oct 15, 2014

Right now new_patchset includes a lot of different actions:

 - new patchset uploaded
 - new patchset uploaded (is rebase)
 - new reviewer added

it would be cool if 'new reviewer added' was its own email type so that it doesn't get buried in the other patchset related mails.
