egroupware/addressbook/inc/class.addressbook_activesync.inc.php
Philip Herbert cbcc4c6c49 updated activesync engine to latest as12.1 code from Andreas B:
- adding better support for non strict protocol implementations to improve device compatibility
- fixing an issue of iOS Mail App crashing, due to server reporting changes not requested by client during message fetch.
- adding support for multiple profiles(with different usernames) on one device to one server. (iOS) 
- Protocol Version 14.1 is now offered to the client
- general improvements to request handling
Updated egw backend and all plugins to be compatible with latest changes to sync engine.

ATTENTION: profiles need to be recreated on the devices.
