Fetch data from S3 bucket!

In this update I save the created user to a text file in aws s3. For now the data is used as a credit list, a thank you to the ones play testing. When I play test in Unity editor it will use a 'stage' bucket with test data. First I blocked all traffic that didn't originate from ich.io but that would stop anyone trying to play the game downloaded (also my build testing).

Playing webgl games via itch client is no good, but their experimental version 'kitch' works well.
