Add 1993/ant/try.txt and ants.txt

The ants.txt file is something that kids throughout the English speaking
world are tortured with, some having been forced to repeat it many,
many, many, too many times, but which fits well here: a grep program
called 'ant' should find lots of ants :-) (and it is a fun use .. or
maybe I just wish to subject others to the torture I was subjected to
decades ago? :-) )
