Minor Upgrades

I've been working on a private fork of the MERN-template to produce a game called Egg Trainer (which you can see here), and I've imported a bunch of improvements from that private fork into this project and it's services. So there's no major changes in how the template works, but I have updated a lot of the libraries used in it.

Edit: A minor upgrade problem from 1.3.0 to 1.3.1 - you must run the following command in the auth server database:

 ALTER TABLE `accounts` CHANGE `id` `index` INT( 11 ) NOT NULL AUTO_INCREMENT;
