Remove storage slot limit and add reset attribute points feature

In the course of 30 hours of play, this caused me a lot of trouble, because there is so much equipment and resources to collect, this limitation is entirely negative.

My suggestion is to remove storage slot limit or open up more slots, such as 50/80/100, and there is no need to unlock to get more slots.

I also noticed that the game currently does not have feature to reset attribute points, and plague ichor can be used to reset attribute points.

Additional: Items with a stack limit of 20 are also negative.
