There are already a bunch of MailNotifier extensions in scripts/master. Consider
putting this in the same file as those.

Honestly, would consider putting this in the same file as MailNotifier. No
biggie either way, though.

Done.
It seems the common pattern here is that every MailNotifier extension is in its
own separate file. I think I'd rather stick to the same pattern, to make it
easier to find the class.

+class ExceptionNotifier(mail.MailNotifier):

"only" is not the word you want here :)

Done.
