Fix chests not keeping content on update 

I'm not sure how much of this code is actually needed but after changing many parts it seems to make the chests keep their contents. Also made it so instead of setting the stack size to 0, if the player is in creative it remains the same, if not it subtracts 1 from the stack size (incase somehow they get a stack of more than 1) All upgrades appear to work and all contents seem to remain in chest. This fixes #31.1
