Get started UI update

Right in the beginning of the snagg journey, we had big ambitions about the visual style of our product. We decided to remove some of the flare to simplify the screens for us to work on. It's been a long time coming but it's back!!!!!!

We've added the background graphics back to the get-started screen. This is something small and easy to miss. Our current users won't even see it but we're hoping the new users will enjoy the UI improvement.
