Unity所有自带style和icon

使用：

直接给字符串给GUIStyle参数，如：

if (GUILayout.Toggle(true, "1", "ButtonLeft")) {};

if (GUILayout.Toggle(newTab == 0, "1", "ButtonLeft")) newTab = 0;
		if (GUILayout.Toggle(newTab == 1, "2", "ButtonMid")) newTab = 1;
		if (GUILayout.Toggle(newTab == 2, "3", "ButtonMid")) newTab = 2;
		if (GUILayout.Toggle(newTab == 3, "4", "ButtonMid")) newTab = 3;
		if (GUILayout.Toggle(newTab == 4, "5", "ButtonRight")) newTab = 4;
