Support JSXSpreadChild

[ehmicky]

See JSX AST tree.

JSXSpreadChild example: <div>{...children}</div>.

Esprima has an open issue with the same problem.

I do not think I will be able to submit a PR for this though, but I still thought it might be beneficial to report the issue.

Hmm, I even commented on PR that introduced it, but don't remember one detail: facebook/jsx#59 (comment) Let's wait for an answer.

Been a while; thoughts on this?

It's been long stabilised, so I'll accept a PR implementing it.
