#50 Improve One Hand Mode navigation

[Remi Ricard]

Also a small suggestion for improvement of the one hand mode: On the
"Adding Record" screen the navigation sequence via the "up" hardware
button currently is: ...price -> cost -> litres -> odometer dropdown box
-> date...
To get to the "km" field where you can actually enter the mileage you
have to navigate to the right from the odometer box.

I think it would be more convenient if the navigation would go straight
up from litres to km to date. And that you have to navigate to the left
from "km" to get to the odometer dropdown box. I guess most people will
rarely or never switch between odometer and trip anyways. Either you use
the one or the other.
