- Deforester now hits forge hooks for tool break, block break, times used.

-Moved deforester not loosing durability from leaves to DeforesterItem instead of Tree mining
- added destroyBlocks method in TreeCutter$Tree for less doubled code
- Mechanical Saws currently break the tree with an empty "hand" as they did before
- Silktouch and Fortune enchants are now being applied from deforesters
