In order to make the license that applies to each file as clear as possible, and to be consistent with elasticsearch, we are adding Apache 2.0 license headers to the top of each file.
Existence of this header is enforced by eslint and tslint and missing headers were automatically added in the last commit by running:
```
node scripts/eslint --fix && node scripts/tslint --fix
```

In webpack 1 the loaders defined here were resolved relative to the file they were going to load, which meant that plugins in other projects could accidentally overwrite the loaders Kibana was trying to use, which is why the aliases were used to enforce proper resolution.
In webpack 2 loaders are now resolved relative to the webpackConfig.context, which is set to the root of the Kibana repo. See https://webpack.js.org/configuration/module/#useentry
