* Adds to docs - deployment with S3/CloudFront

* Tweaks

Loads all files not already handled by other loaders.
Also, switch image loading from file loader to url-loader.

* Added info on using global variables.

See issue #972.

* Fixed typo.

* Moved new section.

* Small tweaks

* Syntax highlighting

* Add Storybook to the user guide

* Add the missing "Snapshot Testing" link.

* Change the title to something nicer

Old title was looks like a marketing pitch. Change it to something looks great.
The new one is: Developing UI Components with React Storybook.

* Mention React Storybook as a third party tool.

* Nits

* Minor changes

Enable sourcemaps in development

* Update css-loader to 0.26.0

* Update the production webpack config

In the `create-react-app` command, try to install packages using Yarn.
If Yarn is not installed, use npm instead.

In `react-scripts`, detect if the project is using Yarn by checking if
a `yarn.lock` file exists. If the project is using Yarn, display all
the instructions with Yarn commands and use Yarn to install packages
in `init` and `eject` scripts.

Upgrade `babel-loader` and remove the cache directory configuration
that was added in #620. `babel-loader` now uses the
`./node_modules/.cache/babel-loader` directory by default, so the
custom config is no longer needed.

* Always build before deploying to gh-pages

* Add line to gh-pages deploy docs about CNAME file

* Remove spaces in npm run command for Windows

* Grammar nit

* Minor tweaks

gh-pages supports https. It's important for prominent help files to encourage best practices.

 - 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.

* Added note about env server restart

As discussed in [#870](https://github.com/facebookincubator/create-react-app/issues/870)

* Style nit

* Create asset filenames mapping on the build output

I use danethurber/webpack-manifest-plugin on Webpack production
configuration to create a file named `asset-manifest.json` which contain a
mapping of all asset filenames to their corresponding output file.

`asset-manifest.json` will be located at the root of output folder.

This'll resolve #600

* Add an explanation for ManifestPlugin

* Make webpack-manifest-plugin's version exact

* Update react-scripts dependencies to use jest 16

* Remove testRegex from Jest config (now default)

* Exit on any errors passed in build stats

* Match console error output in start.js

fixes facebookincubator/create-react-app#824

* Update instructions on publishing to GitHub pages

* Update README formatting
