This PR proves the validity of Axiom L (Löb's theorem for modal logic) under the expected conditions (transitivity and converse well-foundedness). I've also refactored axiom statements to use an abbreviation (IsAxiom), since I started finding the previous way of doing it with manual quantifications cumbersome and error-prone.
