====New Ability for Users to Opt Out of System Emails====
New personal setting for users to opt out of system emails. When set, this will prevent the system from sending any emails to the user where they are the main recipient in the '''TO ''' field. Note that this will prevent the email from being sent entirely so any other parties in the email CC will also not receive the email. Also, this setting does not affect the sending of emails where the user is included in the email CC, password resets, or manually constructed emails such as Group Emails.
