Feature request: Add duration information to Output 1 and 2

[CirruZZ]

It would be neat to have the duration info of the upcoming window when Output 1 and Output 2 fires. This applies s to to all nodes that have Output 1 and Output 2 for sending ON/OFF TRUE/FALSE.

As now it sends
{"payload":"ON"}

Suggestion would be to add
{"payload":"ON", "countHours": 3}

This information is available in payload.schedule of Output 3 but it would be nice to have directly when receiving output from Output 1 and Output 2.
