-Updated the Mod Preview thumbnail to reflect the new eye changes

(last change note for tonight i swear)

-Improved the shape of the eyes so they appear as perfect spheres now

-Upped the brightness on the glowing eyes

-Made the eyes tintable with the Secondary color slot

-Adjusted the regular Daedric Helmet textures to be more compatible with the glowing eyes

-Moved the eyes from the Arms category to Upper Face Props - this was done because if you had the eyes in the Arms slot and rotated your soldiers in the Armory, the eyes would lag next to the helmet and not properly follow it

(sorry about the sudden influx of change notes, i couldn't get the eyes right and it was bugging the shit out of my ocd ¯\_(ツ)_/¯)
