phpmin'd

PHPmin is a genius invention by @robclancy that saves many kilobytes of precious bandwidth which is important in mordern web development.

This will significantly improve the speed of composer update and all websites running laravel.

Since this is a drastic rewrite of all Laravel code, I suggest giving it a new name: Laravel 4.2 v2.0

EDIT: I am aware that tests are failing, but this is a necessary sacrifice for webscale performance.
