Added continent outlines and object occlusion

After spending way too much time trying to figure out webgl and three.js I decided that it was not worth the extra effort for slightly better graphics. Running out of time, I decided to stick to the system that I already had and decided to just draw the coastlines so you can make out the earths orientation better. Right now I have only added N&S America, Antarctica, and Australia. Ill add the rest later but for now this is what I got. Running out of time to ship this so I’m going to add a location selector and call this good.
