Reorder rotaries

[topisani]

Currently, the order of the rotaries is:

R B W G 

Red needs to go to the far right, since its often used as a gain setting with a slider on that side. Also, white stands out, and for that reason needs to either go to the far left, or be included in the middle. Blue makes a good middle option. Main contenders are:

W G B R 

G B W R 

The order of course has to match the settings on screen, so that's the major thing to consider.

Thoughts?
