firstLaunch
Added first launch instructions. Localization is fine, in all the five languages the app supports.
Changed message alertView as global object, to test when the user dismiss it. Added global alertView firstLaunchView, the alert that displays the instructions for the user when the app is first launched.
Commented previous test to see if it was the app first launch. Used bool on the standardUserDefaults singleton to see if it is the first launch. Used timer in order to make VoiceOver read the alert.
