Wear flowers in your hair!

Adds the ability to wear five kinds of flowers (harebells, poppies, sunflowers, moonflowers, and novaflowers) on your head slot.  They even get their own new mob sprites that I made myself.

Aside from looking pretty, they have no practical benefit.

Thanks to Cheridan for helping me with the equipment slots.

The sprite was darkened due to being hard to notice in the mean time.
