autfilt: fix --accept-word

Browse source 
* bin/autfilt.cc: Translate each word as an automaton once,
and do not make a global product of all of them.
* spot/twaalgos/word.cc: Register the atomic propositions used by the
word when converting it into an automaton.
* tests/core/acc_word.test: Add a test case that used to fail, and
another test that make sure some words are not accepted.
