Ralf Gerlich:

- automatic detection of axis directionality, so that axis inputs are appropriately inverted only when necessary
- fixed trim axis names for better understandability
- fixed signs for flaps up/down property increments
- button 0 was previously used for skipping axes and buttons in both loops. Now button 0 can be assigned a binding (e.g., brakes). Instead, moving any axis during the button-assignment-loop indicates skipping.
- The user is now told how to skip a control.
