Add SMS message skill

[tylxr59]

Added SMS skill, based on the telephone skill.

The sentences are setup so you can add your message into the first query ("Send a message to Tyler that says Can you grab cat food at the store") or in two-steps ("Send a message to Tyler" -> "What do you want the message to say?" -> "Can you grab cat food at the store?")
