Title: Lighting

Major changes include:
* A new `SkyBox` with some default assets for stars. Added a few ideas to the [Roadmap](https://github.com/AnalyticalGraphicsInc/cesium/wiki/Stars-Details).
* A new `SkyAtmosphere` that fixes #344, improves performance, and improves the Columbus view transition.
* Primitives are now diffusely lit by two directional light sources attached to the camera, which fixes #255
* A bunch of smaller changes, some breaking. See [CHANGES.md](https://github.com/AnalyticalGraphicsInc/cesium/blob/lighting/CHANGES.md).

Central body shading was simplified making load times significantly faster. Admittedly, when zoomed out, the globe doesn't show the shape as well. The plan is:
* To bring in the [ocean](https://github.com/AnalyticalGraphicsInc/cesium/tree/terrainAndOcean) branch, which, as its name implies, make the ocean look much better.
* Add night lights based on streaming imagery that fade out as we zoom in.
* Longer term - add volumetric clouds.
