Adding Astropix app to the list

Adding another app, sorry for making another PR, I should included this one in the previous PR! :D @AnonymusRaccoon Do you want to add your music player here? ;)

I think this sample is very simple.

These samples have interesting functionality or UI: https://github.com/wcoder/open-source-xamarin-apps#sample

What do you think?

The app consumes a RESTful service, for retrieving the images, the repo for this app is recent, like ~4 hours ago, but it will be evolving as I progress with it. it could be useful to people who wants to consume restful services using Xamarin.Android.

Hmm, I think it is just HTTP GET request used common .NET

You're right, maybe later when the app evolves into something relevant I could make a new PR.
