Added javadoc.

Added strafing.

Streamlined targeting and menu navigation. Both cycle forward and backward and have a select button.

If no controller configuration active then no actions taken(like rendering steering marker).

If a ship system(e.g. burn drive) forbids steering the steering controllers won't generate the blocked inputs.

Null pointer check for selected weapons group in case a ship has no weapons at all.

Fixed inverted axis output.

Presetting the values for configuration properties in case no configuration had been created.

Fixed the need to define all "axis or button" portions in the bindings. Not editing any one of them would invalidate and discard the entire entry.
