Pythonise JS JSON dump

pythonizeJsonDump.js

/*
Python and Node don't stringify JSON object the same way. 
Python adds some spaces after `:` and `,`, causing some trouble if
you try to compute the same hashes across languages.

Here is a Node function turning a Node generated JSON string into
its Python equivalent.
