[BUG] When rotating belts, they cannot rotate down.

[NotSoV]

(Ex: Up, right, up(should be down here), left, up, right, up.)

I still have my training wheels on when it comes to JavaScript. I've applied a duct tape fix for my locally downloaded copy. Something seems to be wrong with the below function in viewmodel.js:

 function rotateSelectedItem() {
    if (selectedItem && selectedItem.canRotate) {
        selectedItem.direction = (selectedItem.direction + 2) % 8;
        pickPlacable(selectedItem);
    }
}

or in view.js:

 function createPreview(placeable) {}

In rotateSelectionItem(), I can cheat and change the 2 to a 1.9999 or something like that and my models will rotate properly, to the human eye, but I am not sure what the ramifications are when exporting the string.

If someone could point me in the right direction, I'll spend the time fixing it. Thanks!
