- session_(dla|action) is stored in egw_access_log table
- notifications refresh via ajax set notification_heartbeat timestamp in egw_access_log
- if notification_heartbeat is set (happens only for browser sessions with popup notification) sessions get removed from session list one minute after browser is closed
- new static method egw_session::notifications_active($account_id) to check if given user has an open browser with notifications popup checking, to ensure popup notifications can fall back to email
--> REQUIRES DATABASE UPDATE / SETUP
- from user perspectiv they are global cat like the existing ones
(also comming in two flavors: global or for a certain app)
- admins can select to limit a global cat when they create it
--> all members of a given group have the cat as a global one
==> This does a silent modification of the categories table:
global cats get changed from cat_owner=-1 to cat_owner=0 !!!
Admin can now define multiple addressbooks each with an own edit / view template and an own icon.
Atm. all Addressbooks are stored in one backend, but this will change soon^tm
