Added a shadow to the space display so hopefully it doesn't look as jarring in the middle of the page and fixed bug where selecting a planet you haven't conquered yet throws a ton of errors.
Fixed bug where space tried to load images of planets with img src by switching it to angular's img ng-src
Added a bunch of new pictures of planets for the existing system and so I can expand out soon ;)
Moved some planets around and added unselectable planets (for sun and earth and maybe moons later....)
