Autocenter & Move do not save

Autocenter and Move use a function of the THREE.js library, which I believe is

``` js
var n = 10;
translateX(n); translateY(n); translateZ(n);
```

or some variation. The problem being it seems these functions do not move the model by changing it's x,y values, but by translating the model in the scene.

To be fixed, it needs to change the values in the model.
