/**
* do whatever is necessary when a page has been updated
*
* This function:
* - logs the update
* - sends notification to watchers and to followers
* - "touches" the container of the page,
* - ping referred pages remotely (via the pingback protocol)
* - ping selected servers, if any
* - and triggers the hook 'update'.
*
* The first parameter provides the watching context to consider. If call is related
* to the creation of a published page, the context is the section that hosts the new
* page. If call is related to a draft page that has been published, then the context
* is the page itself.
*
* This function is also able to notify followers of the surfer who has initiated the
* action.
*
* @param object the watching context
* @param array attributes of the published page
* @param object page overlay, if any
* @param boolean TRUE if dates should be left unchanged, FALSE otherwise
* @param boolean TRUE if watchers should be notified, FALSE otherwise
* @param boolean TRUE if followers should be notified, FALSE otherwise
