3D widgets for Vectors now scale along with the root component of the actor that they are apart of

The 3DWidget that is used to represent a vectors position in 3D space now scales when scaling the actor that it is attached to. This could lead to having a vector that is too small to see/ hard to find. This could also lead to a widget that is overly large, making it hard to place the vector with accuracy.

1. Open editor
2. Create an actor blueprint
3. Open actor blueprint
4. Add a static mesh to the actor (editor cube)
5. Create a new vector variable
6. In the details for the vector check "Show 3D widget"
7. Save a compile
8. Place the actor in the level
9. Scale the cube up and down
10. Notice that the diamond shaped widget changes size as the cube is scaled
