Removed dupe code in 3D init method.

Now using resizeViewport to initialise the camera.
Added a missing semi-colon. My bad.
resizeViewport is now only called once.

It was being called twice during world init.
Removed the cloning of the camera data.
Added the test sphere back in.

But it's in it's own method and not hard coded in the constructor.
Updated the config JSON to point to the Amazon server
Merge branch 'master' of github.com:growse/CRUKGameJamTeamAwesome
