Replace node-fetch with electron-fetch

[mdogadailo]

When a user startshyper, it sends the request to https://hyper-news.now.sh from notifications.js file. If the user is behind the proxy server, this request is going to fail, because in this case, we have to find

• if the user using the proxy
• the configuration of this proxy
• and credentials

(another scenario from Linux auto update)

This pull request replace node-fetch with electron-fetch.

The electron-fetch repeats API from node-fetch (it was forked from last one), but it's using Electron net module, so hyper don't need to care about proxy configuration.
The net module provides

• Automatic management of system proxy configuration, support of the wpad protocol and proxy pac configuration files.
• Automatic tunneling of HTTPS requests.
• Support for authenticating proxies using basic, digest, NTLM, Kerberos or negotiate authentication schemes.

Will this solve #1612 ?

[mdogadailo]

@albinekb I'll try to reproduce #1612 next week if it solves that, I'll reply in #1612.

Dear @albinekb I can't reproduce issue from #1612, looks like there are not a proxy issue.
I tried to replace response (it's possible that proxy server just replace content) from https://hyper-news.now.sh with 503 and 404.
I tried to made redirect. I tried to create 30 sec timeout on response. All good, just error to console.

What's the status of this PR? I'm behind a proxy, and would love for Hyper to be able to check for updates of my plugins, etc.
