Evergreen

Changes:

• Removed forking Birch trees for optimization reasons.
• Reworked Birch trees, they look a little different but are mostly the same. 
  • Chunk generation in Birch Forest biomes are much faster.
• Reworked Oak trees, no visible difference however they generate faster.
• Reworked Dark Oak trees, no visible difference however they generate faster.

Upcoming:

• More optimizations.
• New tree types are most likely on hold until I get the world generation speed under control.
