* blast(_tac) now handles actual object-logic rules as assumptions; note that auto(_tac) uses blast(_tac) internally, too; tuned;

added all_eq, imp_eq (for blast);

improved comments; added all_eq, imp_eq (for blast); basic calculational rules;

handle actual object-logic rules by atomizing the goal;

added atomize_goal / atomize_tac;

(un)fold: CHANGED; added atomize_tac;
