show how to implement product in Python

* wrap/python/tests/product.ipynb: New file.
* wrap/python/tests/Makefile.am, doc/org/tut.org: Add it.
* wrap/python/tests/ipnbdoctest.py: Ignore %timeit results.
* wrap/python/spot_impl.i: Add bindings for
set_state_names()/get_state_names().
* spot/twaalgos/product.cc: Fix computation of properties.
* doc/org/hoa.org: Name.
* NEWS: Update.

when calling for instance the Python version of twa_graph::new_edge().
See https://spot.lrde.epita.fr/tut22.html for a demonstration.
* Automaton states can be named via the set_state_names() method.
See https://spot.lrde.epita.fr/ipynb/product.html for an example.
Documentation:
* There is a new page explaining how to compile example programs and
and link them with Spot. https://spot.lrde.epita.fr/compile.html
* Python bindings for manipulating acceptance conditions are
demonstrated by https://spot.lrde.epita.fr/ipynb/acc_cond.html,
and a Python implementation of the product of two automata is
illustrated by https://spot.lrde.epita.fr/ipynb/product.html
Bug fixes:
* twa::ap() would contain duplicates when an atomic proposition
was registered several times.
* product() would incorrectly mark the product of two
sttuter-sensitive automata as stutter-sensitive as well.
