3.2.1

• 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.
