Add documentation and dependency for Windows (WSL) users

[Zetaphor]

@sGerli has succesfully setup a dev environment in Windows 10 using the Windows Subsystem for Linux (WSL). This required the addition of a patched version of the node-macaddress package.

This package needs to be added to the dev section of package.json, and the README updated to reflect the process for Windows users.

It's not that macadress package, I'll do this later.

Here is the post @sGerli referred to when discussing the fix in Discord.

Removed the package link from my original post since this requires a specific patch.

And here's the comment where he explained the fix:

1.  Install node-macadress (this version only): npm install github:TheBeastOfCaerbannog/node-macaddress.git#43238cd0569573837d4b48a27b3063d287d2968b
2. If you get an error saying that  node-sass/vendor  was not found run npm rebuild node-sass
And that should work if you installed correctly vue cli

Added in #70 , so now this is done
