[deviceorientation] Opposite z-axis for example 7 (#96)

jipodine has just created a new issue for https://github.com/w3c/deviceorientation:

== Opposite z-axis for example 7 ==
Should not the value of z of example7 be the opposite?

Example 7 says
> A device lying flat on a horizontal surface with the screen upmost has an acceleration of zero and the following value for accelerationIncludingGravity:
> 
> {x: 0,
>  y: 0,
>  z: 9.8};

While everywhere, the specification consistently states the orientation of the z axis is down to up.
> Up (Z) is perpendicular to the ground plane and positive upwards.

Even example 8 says:
> A device in free-fall, with the screen horizontal and upmost, has an accelerationIncludingGravity of zero and the following value for acceleration:
> {x: 0,
>  y: 0,
>  z: -9.8};
