[227k] Emitters should not have DefaultTextures forced on Empty/None slots

[Wulfrayne]

There's many examples of content from previous versions of the game that have Emitters that did not fill all the texture slots, and when the array was changed to be dynamic, any blank or "None" slots are now replaced by very visually intrusive DefaultTextures

This should be changed to not do anything on "None" rather than applying a replacement texture

Fixed.
