Store fader values during standby

[Bluesky]

As a user, I would like to have stored the fader values during standby. 

After every standby or restart of the Lampy console, I have to move the faders to top and down position first to call a scene. If you miss a fader you might loose the start of a scene due to this problem.

Hopefully this change will find into one of the next software releases.

Storing fader values ​​in standby mode highlights a common challenge Lampy console users face as well as how introduces new gameplay mechanics that enhance the user experience, just as solving this fader problem can streamline the work of lighting professionals.
