Add missing sprites to teshari for a few misc items.

A few items were missing sprites for teshari, and for my first PR I decided to give a few of the miscellaneous items that were already in the game proper sprites to fit teshari.

Though with the emotional mask, there was only sprites fitting for humans and shadekin, no sprites for the other species IE: Vulpakin, Unathi, etcetc

This is my first code go easy on me, and I'm still not sure if this is how the modular system works.
Code compiled and all that.
