New Prosim function: WX and Terrain brightness

With V2 Prosim has introduced WX and Terrain brightness dimming function. This works like in the real aircraft for both inboard DU´s and the lower DU.

I found this very useful, as approaching in heavy weather with WX-radar on, the WX was always so bright, that the ND datas could hardly been seen. Now the brightness can be finetuned.

I hade to mount 3 dual axis potis and new knobs. The knobs are from Sismo. They had to be painted with RAL 7001, as they where made for the radios and therefore to bright.
