UI improvement: Success message for channel opening

[myxmaster]

Describe your enhancement idea

When a channel was opened successfully, there is a success message on top of the screen with all the text inputs for the channel opening. Since we have batch channel opening, it doesn't make sense to stay in the view where user can enter data for channel openings and I think it is irritating too. ->A blank screen should be displayed instead with the success message and an "OK" button or whatever. We don't need any summary either, because users can just look at the details of their newly opened channels if they need it again (unlikely).
