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

==============
- remove `Z3_bool`, `Z3_TRUE`, `Z3_FALSE` from the API. Use `bool`, `true`, `false` instead.
- z3++.h no longer includes `<sstream>` as it did not use it.
- 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
