added the lemmas pt_fresh_aux and pt_fresh_aux_ineq
(they are used in the proof of the strong
induction principle)

added code to nominal_atoms to collect these
lemmas in "fresh_aux" instantiated for each
atom type

deleted the fresh_fun_eqvt from nominal_atoms,
since fresh_fun is not used anymore in the recursion
combinator
