git mv *.hint -> README.md

There is one exception:

    $ find . -name '*.hint' -execdir git mv '{}' README.md \;
    git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md

Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.

+Judges' comments:
+
+    This program implements a subject a well known Un*x utility whose 
+    original source was considered to be extremely obfuscated by many
+    people, excluding its author.  In fact, this utility one a major
+    inspiration for the formation of this contest.
+
+    The author supplied us with a slightly smaller unformatted version
+    of the program which we include below:
+
+    #define D ,close(
+    char*c,q[512],m[256],*v[99],**u,*i[3];int f[2],p;main(){for(m[m[60]=m[62]=
