Browser launch can still be suppressed using BROWSER=none

* Proxy rewrites Origin header to match the target server URL

* Added comments on rewriting Origin header by the proxy middleware

* Let Jest handle all file types

* Update regexes

* Fix exclusion regex to also exclude files without extension
* Be over-cautious with Windows paths because I'm not sure how Jest handles them

* There is no automatic babel-jest discovery now that we use transsform

* Added functionality to crash the build during CI whenever linter warnings are encountered.

* Updated the docs with a description on how to use the build in CI

* Fixed small typo

* Fixed description of build error.

Added `ws: true` to the httpProxyMiddleware options, and also listen
for the "upgrade" event so that websockets can be proxied immediately,
rather than waiting for an initial HTTP request.

* add logging of existing port process on start

* Move port process wording in start command on to next line

* Color the named processes as cyan in terminal output

* Add handling for multiple processes on a part

- With the currently process filtering, if multiple processes are returned as running on port 3000, this command would fail. This splits apart the process IDing and the process naming, to support multiple processes.
- One curious thing about the bash command to get processes, is that it'll include browsers with a window open on localhost:3000. May want to reconsider that.

* Add process directory to existing port warning

- also moved terminal coloring up, when getting the process, to be able to distinguish the process command from the directory

* Change output color to all cyan, except "in"

* Rename getProcessNameOnPort -> getProcessForPort

- better reflects its broadened scope (both command and directory)

* Add checking if process is a CRA instance, to customize port running message

- moved from using package.json to a regex, for reliability

* Move getProcessForPort to react-dev-utils

- also allowed for breakdown of commands into helper methods

* Add documentation for getProcessForPort

* Add getProcessForPort to list of dev-scripts files

* Use app's package name when CRA app is running on another port

* Filter port process by those listening

- Removed the handling of multiple process IDs since you can filtering by listening process (and not have the browser in the list of processes)
- Trimmed the terminal outputs for better matching (process id) and better terminal output (directory of process)

* Update README on port helpers, to specify only one port returned

* Add ignore of stderr when executing process commands

- Make sure any potential errors don't leak to the user

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.

* remove "Writing package.json" file console output

* make quotes cyan in "Replacing script" console output

* update console log output for Jest, Babel, ESLint update and group them under one statement

* Style nits

issue here #762

Otherwise it makes it an invalid path :(

* Forked react-scripts should retain the binary name

Fixes issue described in https://github.com/facebookincubator/create-react-app/issues/682#issuecomment-248781486.

* Update eject.js
