🔥 SwiftFM repo updated for the FileMaker 19 Data API

Hey y'all. I just updated my SwiftFM repo for the FileMaker 19 Data API.

Notable improvements include support for the new 'validateSession()', and moving the server 'message' into the completion block. So now you can access the message in the closure, where it's more helpful. Better examples as well. Give it a :star: on GitHub if you find it useful. Thanks! :kissing_heart:
