Fixed $class_name issue, auto loader still doesnt work.

Also I currently get errors when I try to include the required files
directly unto index.php. But including the class files within
themselves, and t4esting works fine, eg: including class.controller on
class.view.inc, and class.view.inc on class.home.inc works fine with no
errors, but including class.home.inc on index.php breaks the code.
Still trouble shooting
