[3.1.0] Further cleanup, making standalone work again

- Remove includes call in HTMLPurifier.auto.php
- Relax ConfigSchema treatment in generate-includes.php
- Clean up some empty comments (there are probably more)
- De-indent some extends
- class_exists() should now attempt to use autoload
- schema.ser is now a standalone file
- tests/index.php can be run from any directory
