Did find and replace in TextMate.
```

* Add ReactDOM.hydrate()
* Deprecate ReactDOM.render() hydration in favor of ReactDOM.hydrate()
* Downgrade the warning level to console.warn()
* Warn when hydrate() is called with empty container
* Add forwarding modules
* Codemod to use full package path outside of own package
Files that require modules from a different package than their own now
does so by the npm path name instead of the providesModule.
* Codemod fbjs module dependencies
* Fix gulp module mapping config
This is a bit lame but because of our module rewrite we need to white
list all the paths that we don't *don't* want to rewrite.
This adds precaching to ReactDOMFiber. I.e. adding a handle from the DOM
node to the internal Fiber. This means that we need to expose an internal
handle to the reconciler.
We use duck typing to figure out if it is a Fiber or Stack instance.
The new failing tests are failing because this is now able to actually
fire events onto Fibers and then the result of those events are
incorrect where as they were ignored before.
This is just moving a bunch of DOM files.
It moves things into dom/stack and dom/fiber respectively. The
dom/stack folder remains split into client/server.
Mainly the shared folder is now my best guess for files that
we can reuse in fiber. Everything else will get forked or
reimplemented.
Also moved the event system out of renderers/shared/stack and
into renderers/shared/shared.
