* migration task to update activity.performed_by (with object_id) for logout action (was always user guest instead of the real user)
* activities: use the actual regrouped lines to list filter users (instead of performing a separate SQL query)
In order to avoid loading user context as "guest" and then wait to be in ws_images_uploadAsync function to authenticate and load a new user context. This way we deal with "automatic" authentication in the same place (as apache auth or url auth) and we use the more common user context loading mecanism. Making Community compatible is now much easier.
To avoid duplicating too many lines of ws.php into inc/user.inc.php, I have moved the init of ws.php into inc/ws_init.inc.php
