Session cookie driver changes
- Changed docs CREATE TABLE ci_sessions example to have the PRIMARY KEY of session_id, ip_address and user_agent combined. - Changed DB updates to add WHERE clauses for the ip_address and/or user_agent strings if sess_match_ip and/or sess_match_useragent are set to TRUE.
