Make the short coming of the ShadowDOM more prominent

[arv]

Based on the feedback from facebook/react#1263 it would be good if we could make it even more explicit that platform.js needs to be the first script on your page.

I could add a console.warn if there is any script tags in the page when platform.js is run as well.

I agree that we should try to make this information more prominent.

I think it's worth it, +1.

There are warnings everywhere platform.js is mentioned.

Closing this. Please reopen if you think we need more pointers.
