Moved johmanx10/hylianshield.git to HylianShield/validator.git => v0.6.0

- Prepared HylianShield validator for own project
- Removed custom autoloader and replaced it with an autoloader generated by composer
- Removed the sluggish benchmarking suite
- Removed the commit hook file and placed the contents directly into the Makefile
- Restructured Makefile (allows for easier installations and updates, commit hook is properly integrated in development installation, autoloader is optimized for production)
- Rewrote testing namespace from `\Tests\HylianShield\Validator` to `\HylianShield\Tests\Validator`
- `composer.phar` is now installed locally instead of in `/usr/bin/composer`
