Forgotten request for componentDidCatch

[fusiondesign]

An issue was brought up in facebook/react#10461

which highlighted an opportunity for expansion on componentDidCatch(error, info) - being that info only returns one item prop: componentStack; there were a lot of good ideas to break this down into a detailed object of the error with an array for the stack trace.

This issue was then closed for facebook/react#10922 - which told everyone the issue had moved to a new respository - but the referenced issue missed the very initial reason for the request. We didn't just want documentation, we wanted to look at a fuller featured object for error info.

So it was moved and closed again in #17
