python: add bindings for ltsmin

* python/spot/ltsmin.i: New file.
* python/Makefile.am: Add it.
* python/spot/impl.i: Add bindings for kripke and fair_kripke.
* tests/python/ltsmin.ipynb: New file.
* tests/Makefile.am, doc/org/tut.org: Add it.
* tests/python/ipnbdoctest.py: Make it possible for notebook
to exit(77).
* debian/control: Make the Python package dependent
on libspotltsmin0.
* python/spot/__init__.py: Typo.
