Bug: When launching with an unkown option, ttysolitaire crashes with a
segfault.
Reason: This is due to getopt_long() not knowing where to terminate the search
for matching options in options[].
Fix: Append an additional Element to options[] containing only zeroes. This
is in compliance with the GNU docs. See `man getopt_long` for reference.
