Updated vendor modules.

- Updated the vendor modules to be compatible with updated Apple guidelines for
  advertising and use of tracking identifiers.  This eliminates the use of
  UIDevice 's deprecated uniqueIdentifier method and updates to use the most
  recent versions of vendor libraries that were updated to adhere the new
  guidelines.
