Goop's Birch

Changes the hue of existing birch wood related blocks to be warmer and less yellow.

Birch logs, stripped birch logs, birch planks, birch boats, birch signs, item frames, doors, and trap doors have all been changed.

(all changed textures have been based on existing textures created by Mojang, unless specifically stated as I want this to be as close to the vanilla experience as possible)
