confusing wording in mail.MailNotifier.__init__ documentation

[VZ]

The extraRecipients parameter is currently described as tuple of string but it should really be a list of strings because sort() is called on it later in the code and tuples, unlike lists, don't have this method.

Maybe it's just me, of course, and you're not supposed to interpret "tuple" here as meaning Python "tuple" but I did (even patting myself on the head for noticing that this one parameter was a tuple unlike everything else...) and IMO it's not impossible that someone else will be trapped by this as well, hence it would be better to avoid mentioning tuples here at all.
