Daniel Wright 0a2357f472 Added PrecomputedAOMask material node - allows procedural texturing using Ambient Occlusion computed by Lightmass
* bGenerateAmbientOcclusionMaterialMask must be enabled in WorldSettings for the mask to be produced by a lighting build.  The mask is stored in a BC4 texure which adds half a byte per lightmap texel.
