Edit rarity code for 1.3.2 to the 1.3.3 script

[kristhasirah]

Thanks for your help HoF, sadly din't manage to make it work, i guess i wont be able to upgrade my site, because my site depends completly in the rarity code
thats the adopt page-> I will wait for 1.4.x version and see if the random generated egg is added to the script, or if someone manage to make something similar to the rarity code for this version
