Tough Environment 0.4 - 1.21.1

Block Breaking Restrictions - Makes blocks unbreakable if the player is not using the correct tool.
Stratification Toughness - Makes some blocks that are considered higher strata than stone level blocks require higher level pickaxes to mine effectively.

Improved code for breaking dirt into loose dirt and also added other dirt-like blocks to break in the same way.
General improvements of loot tables for blocks to drop the proper items and remove/fix wrong drops.
Brought back the ability to combine tools to repair them. (will only be modified in the btwr modpack)
Fixed placement code for ore chunk blocks on the ground to work as intended.
Fixed a bug that caused falling(loose) block stairs to turn to their full block counterpart when falling.
Fixed the hardcore mining speed configuration setting in Mod Menu to work properly.
Fixed mining speed of primitive chisels for higher tier ores to be slower.
Fixed mod icon in the creative mod menu to display properly instead of the "missing" texture.
Fixed some chisels making a ding sound on the wrong block breaks.
Changed diamond chisel's crafting recipe to use a diamond instead of diamond ingot by default.
Removed the new texture for copper ore chunk and reverted it to the vanilla original one for raw copper.
Other minor fixes/improvements which should've worked as intended.
