Some patron changes (Patreon)

Hail Barbarians,

We are changing a few things on Patreon.

The Tiers have been slightly changed; here is a short list of the significant changes:

- The "Barbarian" Tier will have only one update per month.

- To get access to the STEAM version of the game, you must, from now on, take the "Barbarian King" Tier.

Thank you again for your barbaric support.
