* Hello 15.6 Release Candidate
**what is the change?:**
We update the versions of all associated React packages when bumping the
version of React.
**why make this change?:**
We want to publish a RC to give folks time to try out the latest version
before it's final.
Why bump the version of every other associated package?
It makes the dependency between them more clear.
There will be cases where we make a fix in React-DOM and it requires
changes in React core. In that case, it will be more clear to people
when we update the versions of both and they remain in sync.
**test plan:**
Visual inspection
**issue:**

* Update a couple more packages versions
**what is the change?:**
Updates version for 'react-dom-factories' package and 'react-addons'
template.
**why make this change?:**
We missed these in the previous commit, which was copying the approach
from https://github.com/facebook/react/pull/9828/files
**test plan:**
Visual inspection, and running the build
**issue:**

This copies modules into three separate packages instead of
putting it all in React.
The overlap in shared and between renderers gets duplicated.
This allows the isomorphic package to stay minimal. It can also
be used as a direct dependency without much risk.
This also allow us to ship versions to each renderer independently
and we can ship renderers without updating the main react package
dependency.
