Better Forests

More naturalistic Acacia trees.

Groups of saplings can grow into the RTG trees. Larger groups, up to 3x3, grow into larger trees. Lone saplings and (when appropriate) 2x2 groups grow vanilla trees.

Trees with mixed blocks can be grown from mixed saplings. The sapling in the center determines the form of the tree; the most common sapling around it the logs; and the second most common sapling around it the leaves (or the most common if there is only one). This can grow Dark Oak and Jungle materials even though Better Forests currently doesn't have trees for them; an Oak sapling with Dark Oak saplings around it will be an oak-shaped tree made of Dark Oak wood and leaves. So, yes, you can farm Dark Oak.

Bugfix: Fewer missing trunk blocks.
