Title: CCEffectLighting - Fix for SB issue #1252

When CCEffectLighting is applied to a CCEffectNode it is unable to access the node's scene (and therefore the light collection) because of CCRenderTextureSprite's unique parentage / ownership. Handle this in a CCEffectUtils helper function and always use that to access the scene.
