print_dot: add xlabel to colored states if too many colors in use

Based on a report from Andreas Tollkötter.

* spot/twaalgos/dot.cc (highlight_states_show_num_): New option,
turned on implicitly when more than 8 colors are used.
* tests/core/highlightstate.test: Test it.
* NEWS: Mention it.
* THANKS: Add Andreas.
