Fixed fences being replaced by leaves.
Spindles no longer stack  and cannot be repaired by crafting together

Fancy Spawn Egg Colors! :D
Creative Tab Organization.
Localization Organization
Added nutrient tool tip to seeds. Only visible with at least expert agriculture skill (same as using nutrient hoe mode).
