Update README.md to reflect status of the skinning abstraction

[SteveALee]

WARNING: As of July 2016, the skinning abstraction is broken due to rapid development of matrix-react-sdk to meet the needs of Riot (codenamed Vector), the first app to be built on top of the SDK

Is there an update on this as of April 2018?

I ask as I am creating an app with ultra simple UI and so this would be useful.

thanks

I now see https://github.com/matrix-org/matrix-js-sdk might be better - given I want to start with simple webRTC only

There is actually an update, the layering has recently been fixed, there may still be bugs with it and its still on the develop branch

Ooh, great. I'll take a look. Thanks
