Hotfix/sns-sms

[chancefeick]

Hotfix for SNS topics not delivering to SMS subscriptions. Result of SNS backend (silently?) failing when hitting SMS length limits from large JSON payloads. The following protocols are supported:

{
  "default": "foobar", 
  "email": "foobar", 
  "sqs": "foobar", 
  "lambda": "foobar", 
  "http": "foobar", 
  "https": "foobar", 
  "sms": "foobar", 
  "APNS": "{\"aps\":{\"alert\": \"foobar\"} }", 
  "APNS_SANDBOX":"{\"aps\":{\"alert\":\"foobar\"}}", 
  "APNS_VOIP":"{\"aps\":{\"alert\":\"foobar\"}}", 
  "APNS_VOIP_SANDBOX": "{\"aps\":{\"alert\": \"foobar\"} }", 
  "MACOS":"{\"aps\":{\"alert\":\"foobar\"}}", 
  "MACOS_SANDBOX": "{\"aps\":{\"alert\": \"foobar\"} }", 
  "GCM": "{ \"data\": { \"message\": \"foobar\" } }", 
  "ADM": "{ \"data\": { \"message\": \"foobar\" } }", 
  "BAIDU": "{\"title\":\"foobar\",\"description\":\"foobar\"}", 
  "MPNS" : "<?xml version=\"1.0\" encoding=\"utf-8\"?><wp:Notification xmlns:wp=\"WPNotification\"><wp:Tile><wp:Count>ENTER COUNT</wp:Count><wp:Title>foobar</wp:Title></wp:Tile></wp:Notification>", 
  "WNS" : "<badge version\"1\" value\"23\"/>"
}

:message_structure allows sending a different message for each protocol. We're only setting a specific message for SMS, then defaulting to the previous payload for the remaining protocols. Would've been nice to use #html for "email", but SNS unfortunately only renders plain/text.

So how does this handle messages that are over the SMS length limit? I can't quite tell from the code.
