Callback response formatting

[shamo42]

Awesome service! About the issue, the response string contains some characters that make it difficult for JSON libraries to parse it properly:

• some extra \n
• \" instead of "
• "{ instead of {
• }" instead of }

This is the response I get:

{"hash": "A3B74654AC5BEBCA1EAD3EDEDAC4EA73A907B30CF9724E20987F0ACD4C78BB55", "account": "xrb_38j81fhhd4qn58k8sps5drn3ubqymcyx7jw5ixftg57kxdem5qbt4h3cnnng", "block": "{\n    \"type\": \"state\",\n    \"account\": \"xrb_38j81fhhd4qn58k8sps5drn3ubqymcyx7jw5ixftg57kxdem5qbt4h3cnnng\",\n    \"previous\": \"78AEF801FA0C714531DB78301B78AD0E67718A38CCECE6DFAC2B64C4190C110A\",\n    \"representative\": \"xrb_1ywcdyz7djjdaqbextj4wh1db3wykze5ueh9wnmbgrcykg3t5k1se7zyjf95\",\n    \"balance\": \"150567889999999999999999998\",\n    \"link\": \"BC692F56B8B5CDA7B325E1DA47BE2D22477C7D1BE29CF31A271F66358437C5A2\",\n    \"link_as_account\": \"xrb_3h5b7xddjfgfnyskdrgtayz4tak9hjyjqrnwyef4g9u88p45hjf4zdibbm5o\",\n    \"signature\": \"A7DABA9DD30D5FB16633F74D84CB6B506BF9322FC5271CDC7EF29524CAA3CDB48D4F5C39DBFD7E16C96651CBEAC3848621CC16DC8C0FF6F7D43C737EF01D5101\",\n    \"work\": \"80000000008b56f6\"\n}\n", "is_send": "true", "amount": "10000000000000000000000000"}

This is the response I expect:
