Poison Madness

Documentation and frog movement change update:

New Documentation book ingame, the poison codex. (suggestion by serene_cori9265089)

Includes almost all that there is to this mod, i haven't finished the documentation but im publishing it so you can check it out and tell me how you feel.

Frogs no longer walk now only rely on jumping around, and in water they swim very slowly by performing small impulses with their legs. (suggestion by Baronman)

New advancement that grants you the poison codex when entering a world for the first time, and also new recipie for this book.
