Changes to PHP

Over the past few months, PHP has had quite a few changes to its API and functionality across most of the functions PHP-Egg uses. Starting with PHP 4.2.0 and continuing with 4.3.0, I was rewriting major portions of PHP-Egg with each release of PHP. Hopefully the major changes to the PHP CLI have paused for a while, and I can begin to release changes that won't be made obsolete by the next PHP CVS update.
