[WIP] Updating code to match PSR standards

Since the README.md suggests that the code should match PSR-0, PSR-1 and PSR-2 I've created this WIP to do so.

Issues that show up will be posted here

* `bootstrap/autoload.php` A file should declare new symbols (classes, functions, constants, etc.) and cause no other side effects, or it should execute logic with side effects, but should not do both. The first symbol is defined on line 15 and the first side effect is on line 16.
