Added Cobblemon from the new V1.5 update

Pretty much all the ones you'd hope for have custom spawns.

Better Nether Compat added.

Not 100% finished, need to add more custom spawns for pre 1.5 update mons.

3.X update plans

• More comprehensive Overworld spawns.
• Refine spawn rates
• Relocate out-of-place spawns
• Hammer out my lapses of judgment
• Update the Wiki (no documentation for the spawns I just added yet)

Pro-tip

Go to Better End's dragon graveyards biome.
