Alexandre Duret-Lutz 0ad62cb97b langmap: adjust to only color non-unique languages
Fixes #203.

* spot/twaalgos/langmap.hh (highlight_languages): Simplify the
interface by only taking the automaton to color.
* spot/twaalgos/langmap.cc (highlight_languages): Only introduce
color for states that have a non-unique language.
* tests/core/highlightstate.test: Update and add more tests.
* tests/python/langmap.py: Keep the tests simple.
* bin/autfilt.cc: Adjust usage and help string.
