Subject: [PATCH] twaalgos: Set 'dicho' algo as default for SAT-based
 minimization

* python/spot/__init__.py: Handle options.
* spot/twaalgos/dtwasat.cc: Handle options.
* spot/twaalgos/postproc.cc: Handle options.
* spot/twaalgos/postproc.hh: Handle options.
* tests/core/satmin.test: Update tests.
Now use 'sat-minimize=4' to use the naive algo.
* tests/core/satmin2.test: Update tests.
Now use --sat-minimize='naive' to use the naive algo.
* tests/python/satmin.py: Update tests.
Now use 'naive=True' to use the naive algo.
