Oily Skin updated

Now Amy has her dose of oil: https://www.patreon.com/posts/oily-skin-mod-24175444

And with this one I think I've finished updating my old mods to Items and Amy DLCs. (If I'm wrong just tell me).

Note about compatibility with HD Feet: The game reads the files in the "~mods" folder in alphabetical order. If you want the oil applied on the HD feet, the files of the oily mods must be read after the HD feet (e.g. rename "Amy_OilySkin_P" to "ZAmy_OilySkin_P").
