Tested and working.

 #pragma strict
 
 var lookSpeed = 15.0;
 var moveSpeed = 15.0;
  
 var rotationX = 0.0;
 var rotationY = 0.0;
 var rotationZ = 0.0;
  
 function Update ()
 {
     rotationX += Input.GetAxis("Mouse X")*lookSpeed;
     rotationY += Input.GetAxis("Mouse Y")*lookSpeed;
     rotationZ += Input.GetAxis("Mouse ScrollWheel")*lookSpeed;
     rotationY = Mathf.Clamp (rotationY, -90, 90);
  
     transform.localRotation = Quaternion.AngleAxis(rotationX, Vector3.up);
     transform.localRotation *= Quaternion.AngleAxis(rotationY, Vector3.left);
     transform.localRotation *= Quaternion.AngleAxis(rotationZ, Vector3.forward);
  
     transform.position += transform.forward*moveSpeed*Input.GetAxis("Vertical");
     transform.position += transform.right*moveSpeed*Input.GetAxis("Horizontal");
 }

 using UnityEngine;
 using System.Collections;
 
 public class Rotation : MonoBehaviour 
 {
     float rotationZ;
 
     // Use this for initialization
     void Start () 
     {
         rotationZ = 0;
     }
     
     // Update is called once per frame
     void Update () 
     {
         rotationZ = Input.GetAxis("Mouse ScrollWheel");
         transform.localRotation = Quaternion.AngleAxis(rotationZ, Vector3.forward);
     }
 }

Add these 2 lines of update to your code and you will achieve whatever you want.

 var lookSpeed = 15.0;
 var moveSpeed = 15.0;
  
 var rotationX = 0.0;
 var rotationY = 0.0;
 var rotationZ = 0.0;
  
 function Update ()
 {
     rotationX += Input.GetAxis("$$anonymous$$ouse X")*lookSpeed;
     rotationY += Input.GetAxis("$$anonymous$$ouse Y")*lookSpeed;
     rotationY = $$anonymous$$athf.Clamp (rotationY, -90, 90);
     rotationZ = Input.GetAxis("$$anonymous$$ouse ScrollWheel");
 
     transform.localRotation = Quaternion.AngleAxis(rotationZ, Vector3.forward);
     transform.localRotation = Quaternion.AngleAxis(rotationX, Vector3.up);
     transform.localRotation *= Quaternion.AngleAxis(rotationY, Vector3.left);
  
     transform.position += transform.forward*moveSpeed*Input.GetAxis("Vertical");
     transform.position += transform.right*moveSpeed*Input.GetAxis("Horizontal");
 }


Change your code with the above code segment. This would help you...
