update npm packages

[eduarguz]

In order to make it work in a completely new project I had to change
in package.json :
node_modules/cross-env/bin/cross-env.js
To -> node_modules/cross-env/dist/bin/cross-env.js
and update laravel-mix package using "laravel-mix": "0.*",
just to let you know and check if it was a global issue or just mine

Thanks! I do have to update the package.json file. Will do it as soon as i get a chance.
