Piranhas and more

This is a mod that add some creatures that looks good.
Items:
- Raw and cooked piranha.
- Raw and cooked snail.
Mobs:
- Piranha.
- Mud jumper.
- Proteus.
- Blind fish.
- Snail. (You can tame it with oak leaves)
- Hermit crab.
- Stick insect. (You can mount him)

Some of the creatures in this mod, are in danger of extinction (of course the stick insect of this mod isn't real) they are the blind fish and the proteus.
I added them to make aware people of species that are in danger of extinction.
