Add a flag to disable the water effect.

This flag was hacked into last year's NORAD Tracks Santa application for low-quality mode.

I also refactored Globe somewhat along the way.
Remove faulty logic from GlobeSurfaceTileProvider when layer removed.

The property is named `renderable`, not `isRenderable`, but it doesn't matter anyway because this code is wrong.  If the property name is corrected, then removing the base layer produces a missing globe instead of the blue globe that you get when you don't add a base layer at construction time.
