Do we want the default to be true?

I think it's pretty safe and not a huge performance hit as it only renders the once. It will even fix materials unexpectedly not looking right because they expect an environment map. So it's a nice feature, that you only need to type 'background` to get.

I'd even be tempted to take it a step further and make background="transparent:true" a default component on <a-scene> or at least add background to the hello-world boilerplate just to get the better behaviour by default.
