* Whitelist files that can be embedded through url-loader

Change the current catch-all loader to use file-loader instead of
url-loader, and exclude common image file extensons. Add another url-loader
for images, configured identically to the original catch-all loader.

Part of issue #1293.

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.

* Fix paths in CSS files when homepage is set to "./"

In the production build, ExtractTextPlugin is used to generate a separate CSS file instead of injecting style through JavaScript. This plugin does not work well by default with nested output structure. To fix it, we give it a relative publicPath pointing to the build folder.

Fixes #1174

* Move path module inclusion right after the other imports

Re: #1174

Revert webpack prod config comments to not refer to dev server.

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

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.

* 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
