New Version Of Mesh Baker With Better Support For Non-Texture Properties

This version offers improved support for non-texture material properties such as _Color and _Glossiness through the addition of TextureBlenders. TextureBlenders are custom scripts that blend non-texture properties with textures as they are being added to an atlas. It is easy to extend Mesh Baker by writing TextureBlenders for custom shaders.

This version also offers support for  multi-object editing for the MB3_TextureBaker and MB3_MeshBaker components.
