Added more transparency + 1 donation tier (Patreon)

Hello everybody! First of all, I'd like to show my humblest gratitude towards all of you who have decided to become Patrons to support the future of Blackimus. I can't thank you enough!

As of today, I have added transparency as to what I will use the donation money for: development funds. Development funds for anything that requires money, such as:

- Paying for voice actors (This has happened already);

- Paying for 3D model commissions (Very likely to happen in the future);

- Monthly/subscription fees for tools I actively use for my animations, such as Elevenlabs - a TTS AI tool;

Also in response to some demands of a bunch of people, I decided to add a new donation tier of 10€. I know some people are willing to provide even more, but I'm not comfortable enough to reach that far just yet.

Thank you so much!
