[Suggestion] Add crafting_machine_tint support to centrifuge

[engin33rguy]

Chemical plants can take advantage of a "crafting_machine_tint" to alter the color of their bubbles and windows. Despite my best efforts when poking around, it seems that the centrifuge is hard-coded to have a green glow as its working animation. It would be awesome if centrifuges supported the crafting_machine_tint field as well.
