Limited bundle searching in AppKernel to one level to prevent finding embedded bundles or files with *Bundle.php
Added simple details population via a Config/details.php file for addons and simple callbacks to static AddonBundleBase::onInstall and ::onUpdate
Fixed issue that prevented addons from being registered with Symfony
Prevented addons from loading menu and routes if not enabled
