Support for LOD cross fade variable

Hi, Thanks for this great tool!
Wishing for the ability of a shader to use Unity's LOD cross fade feature.

Did manage to get it working but only by hacking the shader code and adding the following, hope this helps.

#pragma multi_compile _ LOD_FADE_CROSSFADE

and on the frag used unity_LODFade.x uniform variable to control the dither transparency blend in this case.

#ifdef LOD_FADE_CROSSFADE
clip( BinaryDither3x3(unity_LODFade.x - 1.5, sceneUVs) );
#endif

the ability to do it both as Dither or Alpha would be very useful aswell.
Thanks!!
