JFonS f24f582ba5 Various light culling fixes 
GLES3 changes:
This commit makes it possible to disable 3D directional lights by using
the light's cull mask. It also automatically disables directionals when
the object has baked lighting and the light is set to "bake all".

GLES2 changes:
Added a check for the light cull mask, since it was previously ignored.
