Electron recommends to disable nodeIntegration in BrowserViews.
This PR follows this recommendation and updates the example accordingly.

 Changes:

- disable nodeIntegration
- update dependencies

* Rename page component's class name: Counter => Index, Counter => Other
* Rename counter component class name: AddCount => Counter
* Add counter actions `decrement` and `reset` same as with-redux example
* Modify page link by NavigateTo attr in Page component
* Modify license MIT => ISC same as others in package.json
* Modify README

fixes #4390

* Installing only `babel-plugin-transform-decorators-legacy` didn't work
* It also needs to install `babel-plugin-transform-class-properties`

When changing a page `/_app` can be seen as “updated”,  but the router shouldn’t reload it, because there is an ongoing/going to be ongoing update.

It's better that Counter behave not only `increment (add)` but also `decrement` or `reset`.

* Add decrement, reset handlers and rename add handler in `components/counter.js`
* Add increment, decrement, reset actions to `store.js`
* Rename page component class name: Counter => Index in `pages/index.js`
* Remove needless dispatch count event on getInitialProps in `pages/index.js`
* Format JSX to be readable in `pages/_app.js`
* Remove needless line from `components/examples.js`
* Remove needless spaces in `lib/with-redux-store.js`

* Add name, version, license to package.json

* Remove unnecessary dir key from next's argument
* Add license section to package.json

* Update react, react-dom major version
* Add license section to package.json
* Use isomorphic-unfetch instead of isomorphic-fetch

* Fixed class name in data-fetch example
* Removed needless empty lines

* Added name, version, license keys.

I found build error, so I've updated babel-plugin-module-resolver

Use https instead of http for tachyons URL

The option `"decoratorsLegacy": true` seems mandatory, fails without it:

> The new decorators proposal is not supported yet. You must pass the `"decoratorsLegacy": true` option to @babel/preset-stage-0

* Make sure props.url is immutable

* Add test for immutable url

* Match object instead of string

Fixes the compilation error : 

```
* ./clock in ./components/examples.js
ModuleNotFoundError: Module not found: Error: [CaseSensit
ivePathsPlugin] `/components/clock.js` does not matc
h the corresponding path on disk `Clock.js`.
```

Otherwise you may get a React warning about calling setState() on an unmounted component.

* Add immutable redux example

* Updated readme

* Fix linting errors

* Fix flickering on page change via <Link />

* Remove process.browser check
