add server difficulty option for infinite inventory

Exploring and adventuring are core aspects of the game, but managing inventory can often disrupt the flow and enjoyment of the experience. I have spent a considerable amount of time deciding what to discard to make room for new items, which can be tedious and frustrating. This issue can detract from the immersive experience of the game.

To enhance gameplay, I propose adding an option for an infinite inventory in the custom difficulty settings.

Adding this option to the custom difficulty settings allows players to tailor their experience according to their preferences, making the game more accessible and enjoyable for a wider audience.
