[Nauty] select Hamiltonian graphs

[Brendan McKay]

Indeed, that option is missing.  I will add it and send you the new 
source file.
It isn't worth making a new nauty version for this, but of course it will be
included in the next version whenever it comes.

Since hamheuristic is a heuristic only, the effect of the new option will be
"output those graphs for which a hamiltonian cycle was found".
