Minor Update: Basic sleep meter and more lights

This update adds a feature that should have been in the game a long while ago, the sleep meter. As of right now there's no way to replenish it, but it takes 100 seconds for it to run out. Plenty of time to beat the game still. I also added light poles in front of the house with the key so it's more obvious that there is something over there. Keep an eye out for more updates!
