Some quick fixes

Here are some more fixes! :)

• Quality-of-life: made Alumina reduction easier

• BUGFIX: rebalanced Potassium Oxide + Sulfuric Acid

• BUGFIX: fixed balance of Cesium Carbonate + Hydrochloric Acid

• BUGFIX: non-match materials can now fall down a diagonal slope of filter pixels

• BUGFIX: filters no longer stop horizontal movement (conveyors can push things through)

• MISC: allow building walls using Diamond

More quality of life and other fixes coming soon!
