- the datatype of session_id in sec_session_properties should be the same as the sequence. Without this change, busy sites will run into a overflow (as we did a while ago).
- change type of session_id as well to bigint in the create script
- only variables in a non-top namespace survive session cleanup. The logic of the old code assumed that global variables survive the request-cleanup. now, the cached values is kept in the ::acs::* namespace
- replace call to deprecated proc cr::keyword::new by content::keyword::new
