Title: [5.0] [WIP] Moved From Boris To Psysh

Psysh is better than boris, and more importantly, supports windows, and doesn't have a hard requirement on certain extensions that would cause the framework to be unusable because composer with cry.

This will require an upgrade to super closure 2.0 and class preloader 1.1 too, so this isn't quite ready yet.
