Adds creepers. Like, the things from Minecraft. That's about it.
Creepers can be found in wooded areas and bogs, or anywhere else with foliage. They aren't outwardly hostile but have a 100% chance to turn manhunter when damaged, have a fairly high wildness stat, and are genderless as well as sterile. You can also remove their ability to explode with a surgery!
They'll explode if either close enough to a hostile or when in too much pain, the strength of which depending on their blood pumping stat; if their blood pumping capacity is below 50%, then they'll fail to explode and instead just die on the spot. Although a creeper's explosions aren't fiery by default, they will be if the creeper explodes while on fire.
And before you ask, this isn't explicitly patched for CE and I don't plan on it, but I don't believe anything should be [i]broken[/i].
TODO:
- Make creepers afraid of felines
- Tune their spawn rarity(?)
