New option to reverse the wheel rotation

[chevdor]

8<------------------------ FEATURE REQUEST ------------------------------------

Missing feature

Allow the user to define that the wheel will act reversed when entering the password.
That means that turning the wheel DOWN would INCREASE the numbers.

Justification

Pulling the wheel is easier than pushing it. I guess this is like 'Mouse up looks down' in FPS, some like it one way, some another.

Workarounds

I rotate always the other way around, realize it... and redo it :)
