Optimize Hoppers - Major performance improvement
Removed streams from hoppers and also fixed a mistake in the logic.
When this patch was ported to 1.14/1.15, a line of code was put in
the wrong place which disabled a significant portion of the improvement.

Replaced usages of streams in isEmpty and itemstack checks
Replaced usage of streams in pulling loop
Replaced usage of streams in Lootable Inventory isEmpty() check
Only check for refilling Lootable Inventory when accessing first slot, not all

All of these in general were pretty significant hits, so this single commit
is going to cause tacos to magically appear in front of you every day.

Nom Nom Nom
If you hate taco's, you're not allowed to use this improvement.

Also ignore the renames, pulled a lot of PR's.
