Re: [webrtc-svc] What should the scalability mode be when no scalability mode is specified? (#58)

I don't think we should have an empty string there as it's not a valid `scalabilityMode` and we shouldn't special case it. Missing (undefined) is probably a better choice. As for what it does, I believe it should be up to the user agent to chose a sensible default.

We don't want to have to update all the existing applications so that they do not fallback to L1T1, nor do we want to have all the users understand all the pros and cons of having temporal layers and have to specify it from now on for all the browsers implementing the SVC spec. Experts probably won't care too much about the default value and supply their own default anyway.
