Update app to work with Pebble SDK 2.0

Hi,

This pull-request will update the 8 different apps in your project, so that they can be compiled with the Pebble SDK 2.0. This should enable you to claim the UUIDs in the Pebble store, and have the apps updating automatically once they release the new firmware to the broad public.

I should note that according to the Pebble SDK 2.0 documentation the two UUID's that start with "f" are reserved, so you might have to replace those.
