Pasta's Custom Additions

Added custom spawn pools for Articuno, Zapdos, Moltres, Mewtwo, Mew, Ho-oh, Lugia, Rayquaza, Giratina and Bloodmoon Ursaluna. Edited the spawn conditions of Mega Showdown's Burmy (bagworm), Wormadam (bagworm), Cherubi and Cherrim so that they require any kind of leaf block nearby for them to spawn so you can use slabs to prevent spawns on sky platforms like they should.
