stutter: complement non-det automata via determinization

Browse source 
Fixes #164.

* spot/twaalgos/stutter.hh, spot/twaalgos/stutter.cc: Implement
the determinization, while keeping it optional.
* NEWS: Mention the change.
* tests/core/ltl2dstar.test, tests/core/stutter-tgba.test: Add
test cases.
* tests/core/readsave.test: Adjust.
