Modern 5e - Now with rules for using devices + balance [Fourth Draft]

I've been working a bit more on this supplement, mostly focused on balancing the subclasses (special thanks to /u/birkeland for his/her amazing feedback), and hopefully they're now more balanced. Additionally, I've added new rules for Disabling Devices, Disarming explosives and using electronic devices (hacking, security such things).
