Implement chickens!!!

Sum chickiiiin! Awesome. Should be somewhat easy.

• Room feature (Hatchery, like Portal for chickens)
  • Room generates chickens
  • One tile == 1 capacity (might be a variable), each chicken occupies 1 in capacity (this is a property in object)
  • Generation time is quite fast, might be a variable
  • Start as egg -> hatch -> while(true) peck -> walk do
  • These never leave the room
• Chicken coop, object feature
  • Generate free range chickens
  • These only activate when the room is at full capacity and number of free range chickens is not maxed out (variable)
  • Generation also quite fast, same variable??
  • Spew the egg bouncing about 4 tiles straight, but reacts to obstacles and bounces from them

Free range chickens have the same behavior as the normal chickens but they seem to wonder quite freely. They also have limited lifespan (variable). If you sell a room, I don't know what happens to the chickens the room owns. Probably we could just add a tag that they are now free range chickens as well and time will take care of them automatically.

Ok, the basic implementation is there. With the free range chickens and all. I was not sure about the generation time. The variable default value is 16, so I ended up taking it as a seconds. Initially I divided it with the ticks per second to be closer on what I observed. But that just didn't feel right. I guess it is ok now. At least the creatures can now feed themselves.
