Currency changed from $ to € (Patreon)

In the beginning Dollar was the only currency here. I changed it now to my home currency € because it's what I should do as a European citizen. This resultes into a higher number for everyone that is not paying in €. The values don't change for me. It's still 2€, 5€, 10€ and 25€.
Also I added an annual membership option for everyone.

Btw. have you seen my newest Comic that i post on Instagram? Members get to see the finished pages earlier here.
