Shop system, Quick test and other stuff (Patreon)

Now you can buy items from any NPC that has a shop! 😍😍 (the items you can see in the video are just an example for testing) 😁

Not only that, but we have other small new features:

- A quick test system with 3 difficulties (I added it to the church's water fountain so we could test it) and depending on your result, it will influence the NPCs' story 😁

- We now have a notification system as well, which will make it more dynamic when you have an item removed or receive a result from a test.

- The auto-skip system has also been fixed, there was a small bug that made it not work all the time.

Oh, I also managed to fix the biggest bug that update 0.2 had (sometimes the characters would disappear and the dialogue wouldn't start. I'm still doing more tests, but it seems like I managed to get rid of that for good 😁)
