Fixes #3040: Cache recipe and revalidate it (#3042)

* Fixes #3040: Cache recipe and revalidate it

This caches the last used recipe instead of only the result. Which
allows to revalidate the crafting grid against the recipe itself before
hitting the CraftingManager again. Therefore avoiding a high performance
hit for recipe lookups, just find the potential same recipe again.

* Remove old recipe lookup as forge provides it now.

* Further optimizations.

These are a bit quick'n'dirty and need a better solution with a full
container/gui refactoring. But for now they provide some great benefits
in terms of performance.
