Archive studio functionality added

Whilst just a small improvement, for the OCD amongst you, you’ll be pleased to know you can now archive studios that you’re no longer using (which has the primary benefit of meaning you won’t see them in the new class dialog). We track and listen to every suggestion we get from our clients and know that even little features like this can make someones experience in Influx just that much smoother and we love to deliver these, so enjoy!
