Exception in render() propagates to Xcode

[gaearon]

If I throw inside componentDidMount, I see RSOD.
If I throw in render, I'm being thrown into Xcode and I have to restart (not reload) the app.

This is bad, need to look into it. cc @frantic

I found the same when I accidentally missed a # symbol on a hex colour in my styles. Looks like the exception raised when trying to convert the colour doesn't get caught.

This is no longer an issue
