Added support for embedded textures to the FBXExporter (both binary and ASCII). Also made the FBX-namespaces more consistent (we had both Assimp::FBX:: and FBX::). Since we seem to support two types of embedded texture references (both asterisk+texture_id and filepath) I made the exporter use aiScene::GetEmbeddedTexture for looking up texture reference and integrated @loebl 's modification of the function to support the old ("*1") type of references (https://github.com/loebl/assimp/commit/e217358)
