Added a third wheel scroll direction option: inventory position aware. Scrolling up will push the items into the other inventory if it's above the selected slot, or pull items from the other inventory if it's below the selected slot. Vice versa for scrolling down.
Fixed wrong behavior in containers with custom scaled resolution (thanks @panoskj).
Removed the timestamp comment from the config file and made the item order deterministic.
Fixed lag spikes on opening GUIs that some people had.
The config file is now not being overwritten every time a GUI is opened.
