Added a function to retrieve the client_id for a given sysuser_id to the remotting API: client_get_id($session_id,$sys_userid);

- Better default settings for the "Normal" spamfilter policy.

Modified loadUserProfile function i discovered using mailuser interface from horfic after many tests and debugs functions recive a value iguals to userid field not sys_userid.
I keep sysuser_id testing for compatibility issues no have any idea if this used in another place and added aditional userid test. 
Tested all things and used auto-response with roundcube with this modifications all worked fine.
