* update to modern code style

* var -> cosnt

* set trailing-coma to es5 for prettier

* fix eject for linked react-scripts

* path.resolve => resolveApp

* Read script names from own bin instead of guessing

This fixes ejecting from a fork that uses a different bin script name.

* Fix ejecting for a scoped react-scripts fork

We shouldn't hardcode react-scripts because fork name might differ.
We also shouldn't rely on it being an immediate child because scoped packages are a level deeper.

* Clarify that own* properties only exist before ejecting

* add npm-link support

* - remove extra veriable
- simplify condition

* update code after review:
- remove utils/isReactScriptsLinked
- add appPath and ownPath to paths.js (but only for "before eject" export case)

Enables serving static assets from specified host.

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.

* Resolve app paths from realpath of CWD, fix #637

* Use new resolveApp() for NODE_PATH too

tagging dev-only code (@remove-on-publish-begin/end) and pre-eject-only code (@remove-on-eject-begin/end) #257 (#257)

* Load favicon through html-loader.

Fixes #291.

* Add test for *.ico in e2e test suite

* Configure html-loader to process <link href="...">

* Address feedback on html-loader inclusion.

* Place favicon.ico at the root of the build dir

* Make comment style consistent between prod and dev webpack configs

* Fix html-loader config in dev mode

* Symlink-friendly path resolution

I was having difficulties using a local copy of `react-scripts` and `npm link`ing it into a real world project. This change resolves paths relative to the current working directory (that is, most likely the directory of the app) rather than assuming a certain directory structure.

* Fix relative paths in post-eject case

because I'm an idiot

* Renamed resolveLib to resolveOwn
