Update application to use "Pins" on SDK 3.0 timelines (Pebble Time, etc.)

[zo0o0ot]

Given an existing app UUID, users can subscribe to timeline "pins" and have them integrated into the more modern timeline interface.

Guidelines for integration are here:

It looks like I might need to implement some sort of web service to do this. I might use app engine or one of azure's free tier API endpoints for this.

One of the libraries is in python (pypebbleapi) ---Thoughts, @mikeputnam?

That library might work. It appears to depend upon the python requests library which according to the below Stack Overflow only recently became supported on Google App Engine.

But it also may not. Dunno without trying.
