add Dual Option Flip Switch Logic to the switch

Introducing the new DualFlipClassSwitch() function to make Dual Flip Switch Logic fail proof against exception cases, where user had dark or similar colors active. Resolves conflict between preset colors and switch colors on mobile devices.

We now can have a dual logic switch with two options that we can set in the switch outside of the functon.

Multi Option Flip Switch could be possible too, but that will be another "for each of" function to write in another time....

Happy flip switching everyone !
