Cleans up package.json files for our homepage - Removes comments, superflous commas at the end of objects and arrays and replaces single with double quotes and uses the client's JSON.stringify (or the stringifier at https://gist.github.com/1087317) to reformat the output.
Cannot fix erroneous quotations or unquoted object keys. If single quote strings contain unescaped double-quotes, this may result in errors (not a common use-case for the homepage).
you should rethink the use of eval... can't use it in production with that.
