postproc: fix default for acd and interaction with colored

Browse source 
* spot/twaalgos/postproc.hh (postprocess::acd_): Default to true.
* spot/twaalgos/postproc.cc (postprocess::run): When acd is used
to color an automaton, do not run scc_filter to remove color
from transiant edges.
* tests/python/acd.py: New file.
* tests/Makefile.am: Add it.

- spot::minimize_obligation will skip attempts to complement very
weak automata when those would require too many acceptance sets.
- acd_transform() was not used by spot::postprocessor unless an
option_map was passed. This was due to some bad default for the
"acd" option: it defaulted to true when an option_map was given,
and to false otherwise. This had no consequences on
ltl2tgba/autfilt were some option_map is always passed, but for
instance the parity automata generated by spot.postprocessor in
Python were not using ACD by default.
- Using spot::postprocessor to produce colored parity automata could
fail to color some transiant edges when the "acd" option was
activated.
