Shadows in editor

[Stephan Koppel]

So, every major game engine allow us see how shadows work while we managing models and textures.

I think SSE should have the ability to show how light interact with meshes with shadows (soft and hard).

This is also convenient while testing models with alpha, alpha usually fail with shadows, so no one wants to go back to editor to fix some problems and came back to game to see correction effect

I think we can add it like a part of a scene editor.
