Cardano Brand Guidelines (aka Cardano 2020)

[katomm]

Hello,
based on discussions in #67 I want to share here some slides from the branding guidelines from the "Cardano 2020"-brand. (Which is the current one, clearly recognizable by the closing C of "Cardano")

This is a quick overview trailer btw: https://www.youtube.com/watch?v=E7NbPnaM7ng

We will upload the full guidelines somewhere at some point but it can't be part of this repo because it has a different licence/policy.
