Integrate Flurry analytics

[mrPjer]

Before releasing the app, it is important that we include some kind of app analytics so we can make better decisions about future work on the app.

Basic integration should be simple and can be done by following these steps: https://developer.blackberry.com/native/documentation/cascades/device_platform/analytics/integrate_flurry_analytics_cascades.html

We should also consider adding event tracking (http://support.flurry.com/index.php?title=Analytics/GettingStarted/Events/Blackberry) but this is of lesser priority.
