Move security query generation out of groupWorklistListByCondition into a hook method passed to query generation mechanism. This should speed up things some moe, becuase queries for identical role combination is generated once (and cached) instead of once per occurence.
Add a method to generate inner level queries - now they can be regular queries or security queries.
Now that no security-specific handling is done in groupWorklistListByCondition, SECURITY_PARAMETER_ID is present in criterion dicts, not SECURITY_COLUMN_ID.
