Sam Gateau 738369e21f Replacing glutSolidSphere by a cached Geometry ...

Instead of calling glutSolidSphere, just call Application::getInstance()->getGeometryCache()->renderSphere(...)

- replaced all the instances of "glutSolidSphere"
- Changed the atmosphere shaders so instead of drawing a sphere of the size of the atmosphere, we draw a unit sphere, the vertices get scaled at the right radius in th vertex shader using  fOuterRadius
