don't prepend relative paths with hifi scheme, use quat for location orientation

Something seems odd here.

When you're writing the string for the quat - you write it as x,y,z,w

But... when you read it, you appear to be reading it as w,x,y,z

```
glm::quat newOrientation = glm::normalize(glm::quat(orientationRegex.cap(4).toFloat(),
                                                                    orientationRegex.cap(1).toFloat(),
                                                                    orientationRegex.cap(2).toFloat(),
                                                                    orientationRegex.cap(3).toFloat()));
```

Am I mis reading this?
