honor ap() when counting transitions

Browse source 
Fixing this bug alone revealed another bug: parsing never claim or LBTT
automata did not register APs.  So this fixes both bugs.

This is the first part of #170.

* spot/twa/twa.hh (register_aps_from_dict): New method.
* spot/parseaut/parseaut.yy: Call it for never claim and LBTT files.
* spot/twaalgos/stats.cc: Simplify using ap_vars().
* tests/core/ltl2tgba.test: Add a test case.
* NEWS: Mention the bugs.

* Fix autfilt to apply --simplify-exclusive-ap only after
the simplifications of (--small/--deterministic) have
been performed.
* The automaton parser did not fully register atomic propositions
for automata read from never claim or as LBTT.
* The sub_stats_reachable() function used to count the number
of transitions based on the number of atomic propositions
actually *used* by the automaton instead of using the number
of AP declared.
