4 - Stackable Items and "Farm Fiesta 2024"

Items can now be stacked. Also, the game now uses a variable responsible for the maximum number of items in one stack.
I'm also working on sorting through stacks of items and stuff...

By the way! I decided to participate in 🌾 Farm Fiesta 2024 - Quirky and will try to release updates productively as part of this game jam
