Do Not Invoke Getters Implicitly - Hide it behind explicit UI

[sebmarkbage]

Enumerating over the keys of an object currently invokes all getters on that object. Which can cause all kinds of issues. We should use getOwnPropertyDescriptor here instead. If it's a getter we should wait to invoke it until explicit told to. Chrome has a little (...) UI that you can click to invoke the getter.

That makes it safer to browse around while debugging an issue without having to worry about state changing and therefore changing the thing you're trying to debug.

I believe this will be solved by #569.

@sebmarkbage @gaearon Yep, this is how it works now, awaiting for review and merge

React DevTools has been rewritten and recently launched a new version 4 UI. The source code for this rewrite was done in a separate repository and now lives in the main React repo (github.com/facebook/react).

Because version 4 was a total rewrite, and all issues in this repository are related to the old version 3 of the extension, I am closing all issues in this repository. If you can still reproduce this issue, or believe this feature request is still relevant, please open a new issue in the React repo: https://github.com/facebook/react/issues/new?labels=Component:%20Developer%20Tools
