Cold Feeders

Simple little mod that adds 2 additional animal feeder options to the game. One keeps food refrigerated, the other Frozen. Both require electricity to be operated and each is unlocked after research is completed on the applicable technology (Refrigeration and Freezers, respectively). There have been a few mods that did this, but none which are both up-to-date and standalone. I'm a horrible artist, so I just used the base game models for the feeders.
