* Enable useBuiltIns option on object-rest-spread

* note polyfill requirement

* Enable useBuiltIns with transform-react-jsx

* Add direct ref to transform-react-jsx

* Update `babel-plugin-transform-object-rest-spread` to v6.19.0

The `babel-plugin-transform-object-rest-spread` v6.19.0 update will
allow us to remove the `babel-plugin-transform-es2015-destructuring` and
`babel-plugin-transform-es2015-parameters` as the object rest spread
transform will now work standalone and not require additional tranforms

* Remove unnecessary babel transform plugins from babel-preset-react-app

The `babel-plugin-transform-object-rest-spread` v6.19.0 update makes
these plugins unnecessary, as v6.19.0 can be used stand-alone

* Update babel-preset-env to 0.0.8

Changes between 0.0.6 and 0.0.8 should be backwards compatible:
https://github.com/babel/babel-preset-env/blob/master/CHANGELOG.md

* Use `node: 'current'` as target for babel-preset-env

This replaces the hand-rolled node version setup with a new feature that
was introduced in babel-preset-env@v0.0.7

https://github.com/babel/babel-preset-env/blob/v0.0.7/CHANGELOG.md

 - babel-preset-react-app@1.0.0
 - create-react-app@0.6.0
 - eslint-config-react-app@0.3.0
 - react-dev-utils@0.3.0
 - react-scripts@0.7.0

* Update dependencies

* Use published version of eslint-config-react-app for development

We dogfood on our eslint-config-react-app by using it as our ESLint config,
but installing it from the local folder causes problems when its peerDependencies
are updated, because npm won't update it unless the version number changes.

Use the published version for dogfooding so it can be installed from npm.

* Enable babel parameters/destructuring for all versions of Node

* Add more descriptive comment explaining plugin use

* Disable ES2015 transforms based on node version using babel-preset-env

* pass major version number for node to babel-preset-env instead of version string

* use parseFloat() instead of parseInt() to parse node version

* fixed style nits

 - babel-preset-react-app@0.2.1
 - create-react-app@0.5.0
 - eslint-config-react-app@0.2.1
 - react-dev-utils@0.1.0
