Tier benefit changes (Patreon)

Due to the new online tax policy now also apply to patreon, I have changed some details in tier benefits in order to hopefully save everyone money:

- exclusive patreon version are now early access patreon version. For supporters it will mostly stay the same, we are updating partreon version weekly to add new content, polish or problem fixing.

- Public version now also have nsfw content (may turns on and off in game menu). Public version will not be updated regularly like pateron version, and content wise will always be behind compare to patreon version.

- Level 1 and 2 tier are now pure support tier, other benefits stay unchanged.

As said before, these changes are made in hope of reduce extra taxation on supporters.
Feel free to ask questions about the change, and thank you for your support and understanding!
