* Fixed default `yum_repo` key in `php::repo::redhat` * On Ubuntu precise we now use the ondrej/php5-oldstable ppa. This can be manually enabled with by setting `$php::repo::ubuntu::oldstable` to `true`. * `$php::ensure` now defaults to `present` instead of `latest`. Though, strictly speaking, this represents a functional change, we consider this to be a bugfix because automatic updates should be enabled explicitely. * `$php::ensure` is not anymore passed to `php::extension` resources as default ensure parameter because this doesn't make sense.
