アセットのSlate, BlendShapeの候補が出てこないのでとりあえず対応

[Slate]CharacterInspector.cs

foreach(var shape in expression.blendShapes.ToArray()){
						GUILayout.BeginHorizontal("box");

						GUILayout.BeginVertical();
						var skin = shape.skin;

						// me
						skin = character.GetComponentsInChildren<SkinnedMeshRenderer> ().Where (s => s.sharedMesh.blendShapeCount > 0).First ();

						var name = shape.name;
						var weight = shape.weight;
						skin = EditorTools.Popup<SkinnedMeshRenderer>("Skin", skin, skins);
