• the long term plan is to get rid of the actor_id parameter to feed.publishTemplatizedAction. for the case where the actor_id was a page_id, this introduces a separate "page_actor_id" parameter to do the work. If you use page_actor_id, you don't need a session key; if you don't use that, then the session key owner will have to be the actor. In the short term, though, to allow apps to migrate over, we're still supporting the actor_id parameter. in theory this shouldn't break any applications. starting in 2 weeks, we'll start checking if actor_id != session key owner, and if so return a "warning" (succeed the call but return false or throw an exception or something like that). starting in 4 weeks, we'll start ignoring the actor_id parameter entirely.

• update the php client library to match the new parameters for feed.publishTemplatizedAction (actor_id gets replaced with page_actor_id). this also adds support to the client lib for data.getCookies and data.setCookie.
