Use Legacy Swift Language Version

Use Legacy Swift Language Version

[loretoparisi]

[UPDATE]
If I add both to MessageGroups target and Pods/NMessenger the flag to NO, I get some few errors, that Xcode helped me to resolve one by one in the editor.

[DavidSchechter]

Please look at this issue CocoaPods/CocoaPods#5864
This is a cocoapods issue and not a nmessenger issue

@DavidSchechter yes thanks I have solved it, "faking" the requested Swift 3.0 update by Xcode, that didn't change anything actually, setting the Use Legacy Swift Language Version to NO explicitly, and solving by hand some errors in the ViewController.swift

This is the diff requested by Xcode8
