HTML_CSS : The Definitive Guide

Upgrade requirement to PHP 4.3.0 and PEAR 1.5.4 (to avoid security vulnerability)

Coding Standard fixes: (errors/warnings) following recommandation by PHP_CodeSniffer

Unit test suites migrated from PHPUnit 1.x to 3.x

API 1.4.0 introduces new setter/getter PHP5 facility compatible (magic function __set, __get) for read/write CSS options.

Error handler allow now to use PEAR_ERROR_CALLBACK (local to HTML_CSS) to customize action when an error/exception is raised. No more need to use global PEAR::setErrorHandling.
