New shaders for GLIcoSphere

GLIcoSphere now has its own shaders.
Set the clear color to black
Added coloring to GLIcoSphere

Coloring is now available on GLIcoSphere. Currently it makes an earth
like planet coloring with more blue verts then green ones.

to provide better maintainability.

Set LoadShaders to use the new IcoSphere shaders.

Refinement is now done with entityID levels to test varying degrees of
refinement.
