Jsfiddle templates should supply renderer.domElement to OrbitControls

Thanks @EliasHasle! And sorry for the delay, this totally slipped my mind.

We should update these to use modules at some point too I guess, or provide module and non-module versions.

EDIT: I’ve taken the opportunity to update the Question category sticky.

I’m thinking it might be more useful to have templates in Codesandbox or Glitch that show how to load a model rather than dev/master branch. What do you guys think?
