Improve table describing FMU differences

@@ -48,16 +48,18 @@ The Pixhawk project has evolved the FMU design through a number of verisons.
 These are named using the designation: FMUvX (e.g.: FMUv1, FMUv2, FMUv3, FMUv4, etc.).
 Higher FMU numbers indicate that the board is more recent, but may not indicate increased capability (versions can be almost identical - differing only in connector wiring).
