Placeable Fixes Beta

Beta version. I have not tested it on all maps, or in MP. I do not know if it works on consoles.

Fixes the placement of Animal Husbandry, Water Tank, and Workshop.
-- Removes the horrible grass borders.
-- Will not overwrite the underlying ground texture.
-- Removes the insane terrain editing costs.
-- Place _almost_ anywhere.
-- Removes the food messes. No more cleaning up 10x a day.
-- Hopefully fixes the "no more space for eggs" issue.

Important!
-- There is no height checking. Be careful with placement and check the height, else it will float in the air.
-- Use the 2 Terrain Levelers included. 50x50 grass and concrete. No need to sell them, just place the animal pens on top.
