Snek's Improvements and Consistencies

Improves and adds consistency to Minecraft's textures without drastically changing them and still keeping their default feel. This is achieved in multiple ways, such as: ### Accurate item icons.  ### Consistent color palettes.  This is best seen with Iron, all Iron is the same color.  ### Logically animated textures.  ### Eating animations for all consumables.  ### Hunger previews and Painting previews.  ### Tools visibly take damage.  And much much more! Feedback and criticism is always welcome.
