Remove 1986/hague alt code, make main entry

I fixed it so that the form where it would segfault (after printing the
correct output) no longer occurs.

The thanks file has had a note added towards the top about changing to
fgets(), noting that although more is mentioned in the FAQ, it can be a
real problem with some systems. The best example of it being beneficial
is 1990/tbr. Naturally I also updated the thanks file for 1986/hague
too, updating the details.

-Cody added alt code that uses `fgets()` to avoid alarming and annoying warnings
-about `gets()` being unsafe. The reason this is alt code, at least for now, is
-that although it will print the results in both forms of invocation, after the
-output in one invocation form it will segfault. This might be addressed later on
-or it might be decided that it is worth it, with a caveat in the Makefile or at
