Implement auth server in PHP

- [x] Auth Server Library
- [x] Logic to update Minecraft codes
- [x] Command to start server
- [x] Read favicon from disk/description from config file
- [x] Remove NodeJS depenency on running the application

also included lazy loading + updates to fit the new skin cache + new command to update database schema. Not all NodeJS stuff is replaced yet, need to create a way to edit config files separate from grunt and it will be complete
