PHP 4 Documentation Moved To Appendix

All, For those of you not on the commit list, I went ahead and moved the PHP 4 OOP documentation to the appendix. This is a reflection of the discussion we had where it was expressed that the PHP 5 OOP documentation should be perceived and treated as the only documentation for PHP's object model. However, to ensure that anyone that relies on PHP 4 can still find appropriate documentation, the PHP 4 documentation would be moved to the appendix. This is the right direction to go with the PHP documentation, as it takes the confusion out of having two very different OOP sections. Brandon
