WebGUI::Inbox::Message::create now passes isInbox flag to WebGUI::Mail::Send::create
so that per-user notification settings get used
SMS Gateway setting field is now 'text' instead of 'email' so that user can enter a
properly formed value (such as 'myemailgateway.com', which is not an email address).
Added SMS notification template as distinct from email notification template because
SMSs should not be HTML and in general you will want to make your SMS notification
message a lot shorter than your html email notification message (160 char limits in
many countries). As a result, SMSs are now sent as separate emails to gateway rather
than being CCd on email notification.
Added smsGatewaySubject setting because many SMS Gateways use email subject for
authentication. For consistency, also added Email notification email subject.
Fixed handling of different combinations of site-wide sendInboxNotificationsOnly with
per-user receiveInboxEmailNotifications and receiveInboxSmsEmailNotifications.
* sendInboxNotificationsOnly && receiveInboxEmailNotifications = email notification
* sendInboxNotificationsOnly && !receiveInboxEmailNotifications = no email
* !sendInboxNotificationsOnly = ignore receiveInboxEmailNotifications
* In all cases, SMS is optional and only dependent on receiveInboxSmsEmailNotifications
Updated tests and i18n
