Subject: [PATCH] Make entities look for hoppers
Every tick hoppers try and find an block-inventory to extract from.
If no tile entity is above the hopper (which there often isn't) it will do a bounding box search for minecart chests and minecart hoppers.
If it can't find an inventory, it will then look for a dropped item, which is another bounding box search.
This patch eliminates that expensive check by having dropped items and minecart hoppers/chests look for hoppers instead.
Hoppers are tile entities meaning you can do a simple tile entity lookup to find the nearest hopper in range.
Pushing out of hoppers causes a bouding box lookup, which this patch replaces with a tile entity lookup.
This patch may causes a decrease in the performance of dropped items, which is why it can be disabled in the configuration.
