This helps recursive implication checks.  Also order
atomic propositions with strverscmp().

* src/ltlast/formula.hh (formula_ptr_less_than_multop,
is_literal, atomic_prop_cmp): New.
* src/ltlast/formula.cc (is_literal, atomic_prop_cmp): Implement them.
* src/ltlast/multop.cc: Use formula_ptr_less_than_multop.
* src/ltltest/isop.test, src/ltltest/ltlfilt.test,
src/tgbatest/det.test, src/tgbatest/dstar.test,
src/tgbatest/explicit.test, src/tgbatest/explpro2.test,
src/tgbatest/explpro3.test, src/tgbatest/explprod.test,
src/tgbatest/nondet.test, src/tgbatest/tripprod.test: Adjust tests.
* NEWS: Mention the new order.
