Feder's Scarecrows

Changelog:

- Added Guardian Scarecrow. Can repel Enderman.

- Added 3 new costumes: Wolf Costume, Ocelot Costume and Guardian Costume.
   These replace the original system for creating new scarecrows. Now, you just right click with the costume to add it on, instead of craft a whole new scarecrow.
- Added recipe for Guardian Costume (Wolf and Ocelot Costumes stay with the same recipe, but with leather helmets)

- Removed the item forms of the Wolf Scarecrow and Ocelot Scarecrow.

(This is a port of Feder's Scarecrows for 1.17.1)
