Added python 3 script to sort entries in README.md

+    The approach taken is explained below. I decided to do it simply.
+    Initially I was considering parsing the data into some sort of
+    structure and then generating an appropriate README. I am still
+    considering doing it - but for now this should work. The only issue
+    I see is that it only sorts the entries at the lowest level, and that
+    the order of the top-level contents do not match the order of the actual
+    entries.
+
+    This could be extended by having nested blocks, sorting them recursively
+    and flattening the end structure into a list of lines. Revision 2 maybe ^.^.
