autfilt: add highlighting options for nondeterminism

Browse source 
Fixes #123.

* bin/autfilt.cc: Add options --highlight-nondet-states=NUM,
 --highlight-nondet-edges=NUM, and  --highlight-nondet=NUM.
* spot/twaalgos/isdet.cc,
spot/twaalgos/isdet.hh (highlight_nondet_states,
highlight_nondet_edges): New functions.
* tests/core/det.test: Add test cases.
* NEWS: Mention them.
