This reverts commit 2dcc448.
We've raised the minimum version of PHP because of a PHP bug before 5.3.4: https://bugs.php.net/bug.php?id=52083 https://bugs.php.net/bug.php?id=50027
5.3.3 has some interesting fixes and this is the version used by Redhat 6 and Debian 6
* Switched to Composer to manage "dev" dependencies * Fixed READMEs * Excluded vendor in phpunit.xml.dist files * Fixed message in bootstrap.php files * Added autoloader for the component itself
…and target dirs
