This commit splites email notification settings in two
parts - one with heading "Email message notifications"
containing batchning period, message-content and
organization-name settings and the other with heading
"Other emails" containing login, digest and marketing
emails settings.
Fixes#19717.
We change the label of various organization settings
to specify moderators.
Labels for 'admins only', 'admins and moderators'
and 'nobody' are still same.
The updated labels are -
- 'Admins, moderators and full members'
- 'Admins, moderators and members'
- 'Admins, moderators, members and guests'
These options will be replaced by user groups in
future but this is an intermediate fix.
Fixes#19562.
