* Automata property bits (those that tell whether the automaton is
deterministic, weak, stutter-invariant, etc.) are now stored using
three-valued logic: in addition to "maybe"/"yes" they can now also
represent "no". This is some preparation for the upcomming
support of the HOA v1.1 format, but it also saves some time in
some algorithms (e.g, is_deterministic() can now return
immediately on automata marked as not deterministic).

* The automaton parser now accept negated properties as they will be
introduced in HOA v1.1, and will check for some inconsistencies.
These properties are stored and used when appropriate, but they
are not yet output by the HOA printer.
