clarified db content: avoid redundancy of historic ML_IDENTIFIER;

merged

proper filterNot, not filterNot-not;

option build_hostname allows to change hostname easily;

clarified permissions of build.db, following server.db;

enforce rebuild of Isabelle/ML, after various changes to build database management;
