Message:

Emails: chunk notification emails into 40 Bcc'd recipients.

This commit introduces the bbp_mail subfilter, used to target bbPress specific emails in conjunction with bbp_get_email_header() to help identify emails that came specifically from bbPress actions.

The purpose of this change is to help forum owners avoid their outbound emails being marked as spam, due to the high number of users that can be subscribed to any given forum or topic.

This change (combined with r6725) goes a long way towards improving the success of subscription emails reaching their intended recipients.

Fixes #3260. Props danielbachhuber.
