Consistent SpawnEggs

Differently sized spawn eggs always seemed illogical to me - should the Ender dragon egg really be the same size as a cow egg? I decided to fix this injustice once and for all.

Now all eggs are distributed into three clear categories based on the size of the corresponding creature:

• Large eggs: Ender Dragon, Warden and other impressive mobs
• Medium eggs: Cows, sheep and other standard-sized animals
• Small eggs: Bees, allays and other miniature creatures

Additional Improvements

Along with the size reorganization, I made other useful changes:

Simplified the design of some eggs that were so overloaded with details they barely maintained their egg shape.

Removed the water puddle effect since I consider it unnecessary for the visual perception of spawn eggs.
