* CNcnOutboxSender

* Sends sms messages from the outbox when offline is changed back to online.

* It only tries to send message once. If sending fails due to other reasons

* than offline mode, then it is up to the user to go to outbox and send it.

* Note: At the moment only sms'es are sent. MMS messages are sent by mms mtm

* and emails are saved to outbox as 'During next connection' and those must

* not be sent.
