* spot/twaalgos/sbacc.cc: Do not label rejecting SCCs with the empty
mark, as it might be accepting.
* tests/core/sbacc.test: Add test cases.
* NEWS: Mention the bug.

* spot/twa/twa.hh: Add support.  Make two constructors for prop_set in
order to diagnose constructions with 5 arguments.
* spot/parseaut/parseaut.yy: Adjust diagnostics for complete and
deterministic.

Part of #212.

* spot/misc/common.hh (SPOT_DEPRECATED): Improve support current
compilers and options flags.
* spot/twa/twagraph.hh, spot/graph/graph.hh (is_alternating): Mark it
as deprecated.
(is_existential): New method.

* NEWS: Mention the renaming.

Algorithms that remove transitions can turn a non-deterministic
automaton into a deterministic one, so we need to be able to specify
that determinism can be improved (as opposed to preserved).

* spot/twa/twa.hh (twa::prop_set::improve_det): New attribute.

This is still missing tests.

Rename tgba_digraph as twa_graph.

* src/tgbaalgos/dotty.cc: Here.
* src/tgbaalgos/sbacc.cc: Make the produced automata as state-based.
* src/tgbatest/readsave.test: Add a test.

... into copy_acceptance_of().  For #65.
