not logged in for the request, the system locale will not be set and text

Change recipients active/total count on update

With the advent of the MANIFEST file, files which are rewritten when
deployed, such as those which have the GIT hash in the query string to force
browser reloading, were no longer deployed unless the content of those files
changed.

This patch adds a flag to the MANIFEST file to indicate that the file was
rewritten when it was deployed. This allows the file to be deployed and
rewritten again when the deployment is run, but also adds an indication
to the console output to distinguish deploying changes as opposed to
deploying rewrites.

This feature adds a setting to the control panel to require signing in to
view attachments. This is in addition to the security already provided in
the download URLs. Currently, download URLs are signed for a specific help
desk, and automatically expire after about 24 hours. The exact timing is the
following midnight allowing for at least 12 hours cache time.

Administrators can impose this extra security feature to refuse serving
attachment files if the user is not currently signed in. This could prevent
third-party users from viewing an attachment if they were able to get access
to the download URL before it expired.

If the Return-Path header does not match the From header, emails are significantly more likely to be blocked by spam filters.

This patch forces the return header to match the from address without having to change php.ini and therefore works properly on servers that have multiple apps sending from multiple email addresses for example shared hosting, multiple support emails in one instance etc.
