add options for logging learned lemmas and theory axioms

Browse source 
- add solver.axioms2files
  - prints negated theory axioms to files. Each file should be unsat
- add solver.lemmas2console
  - prints lemmas to the console.
- remove option smt.arith.dump_lemmas. It is replaced by solver.axioms2files
