From a report by Anton Pirogov.
* NEWS: Mention the bug.
* spot/twaalgos/stutter.cc: Fix it.

* THANKS: Add Anton.
Fixes#333.
* spot/twaalgos/remfin.cc, spot/twaalgos/remfin.hh,
spot/twaalgos/totgba.cc: Adjust. The assert() added
to remove_fin() triggered a lot of failure in the test
suite before the different functions were fixed.
* tests/core/remfin.test, tests/python/tra2tba.py:
Adjust expected result.
* NEWS: Mention the bug.
spot::acc_cond::mark_t is implemented as a bit vector using a single
unsigned, and implicit conversions between mark_t and unsigned may be
confusing. We try to use the proper interface.

The bug is mentioned by Maximilien Colange in a comment to issue #317,
but turned out to be unrelated to that original issue.
* spot/twaalgos/totgba.cc (dnf_to_streett): Save the correspondence
between the created states an the DNF clause in a named property.

property.

property. Relying on seen marks and trying to deduce the matching
original clause could only work from plain Rabin.

paired_with, and do it once per pair.
