RPC call info_actions_folder seem to work almost perfectly

Use ccnpeek to test:
    ccnpeek -c /localhost/<your-user-name>/chronoshare/<folder>/info/actions/folder/<nonce>/%00
or
    ccnpeek -c /localhost/<your-user-name>/chronoshare/<folder>/info/actions/folder/<specific-folder>/<nonce>/%00

+ json_spirit used to format the whole message, not just parts
