Updated CocoaPods to 0.22.1

Updated CocoaPods (the gem) from 0.20.2 to 0.22.1 (latest) and ran a clean `pod install` (on an emptied Pods dir).
Updated installed pods

Updated the installed pods (`pod update`).  Looks like the net result of this is that FontAwesomeFactory went from version 1.1 to 1.2.
