Adds and Implements CE Hardsuit Sprites and Item Icons

The CE hardsuit, while still being modkittable, will now take on the
appropriate sprites of the species it's being modified for.

Added Unathi and Tajaran mob and obj sprites for the helmet and suit,
created and added an 'on' (flashlight) state sprite as well.
