Notify user if all staff are offline

[eartharoid]

If all staff are offline when a ticket is created, or when the user sends a message (after some time since the last offline notification), send a message telling the user that no one is online and it may take longer than usual to receive a reply.

Also, add optional support hours (& days). If a ticket is created or a message is sent in a ticket outside of these hours, such as on the weekend, send a message telling the user when staff will be available.
