Implement Page Home

[borzel]

The "HOME" page should contain a signature feature.

Instead of an overview of the curent channel (like in Behringers original firmware) we should implement some catchy thing.

My Idea is to implement 6 channelstrips that ca be controlled via the 6 display encoders.

• The encoder button could be used to switch between different functions -> Volume, Panorama, Solo, Mute, ...
• The Utility button should open the settings for that page -> selecting channels/parameters, ...

first try, just with the encoders and 6 labels:

Implemented 6 VU-Meters:

The next step is to make it configurable, but this depends on the implementation of the surfacemanager -> #56
