Removing reserved main::

Hey, Edin pointed out that we no longer need to reserve the "main" keyword in zend engine 2. As the main:: keyword was only reserved for the main:: namespace in the first place. We no longer have namespaces, therefore we no longer need to reserve main. Attached is a patch to zend_compile.c that removes main. I'll commit it to zend_compile.c unless someone objects. -Sterling -- "A business that makes nothing but money is a poor kind of business." - Henry Ford
