Merge Elfs: building A LOT of elfs homes!

There are 2 ways to fix the problem of "All elfs are sleeping." The first is to get more elves, which can be harder to do the further along you get in the game since eggs become more expensive. The second way is to create more efficient elf homes. More higher level homes means more elves resting faster! ^_^
(For any Dr. Seuss fans out there, I always think of "The Sleep Book" where he scribes the wonderful hotel in which the beds are so comfortable that people "sleep quicker." LOL)
