* src/tgbatest/spotlbtt.test: Exercise -fx.
* wrap/python/cgi/ltl2tgba.in: Support Couvreur/FM with exploded

Do not treat true and false specially. Otherwise it breaks
translation of F(false).

use true as acceptance condition.
* src/tgbaalgos/ltl2tgba_fm.cc (ltl_trad_visitor): Use Acc[b] as
acceptance condition for Fb, not Acc[Fb].
After this change, degeneralized automata are 40% smaller
with same destination and acceptance conditions directly, without
calling a->merge_transition(). If one transitions goes to "True",
subtract its conditions from all other transitions; this optimizes
a U b.
(tgba_explicit::merge_transitions): New method.
* src/tgbaalgos/ltl2tgba_fm.cc (ltl_to_tgba_fm): Factorize all
variables (not just Next and A) when computing prime implicants,
