z_tilt - corrected values

[jokker87]

z_positions is supposed to be the virtual nozzel-position of the z-axis, in this case the stepper's rod position.

i also needed to switch the positions for z0 and z1, as it moved the wrong z-stepper to level the z tilt. maybe i'm just unlucky and the stepper got connected the other way around on the motherboard in the factory.

moving the points nearer to the center point speed up the process and resulted in more accurate z tilt leveling.

please let me know your opinion on the subject.
