public GameObject ExplosionPrefab;
public Rigidbody projectilePrefab;

// Use this for initialization
void Start () {

// Update is called once per frame
void Update () {

	if(Input.GetButtonDown("Fire1"))
	{
		Rigidbody hitPlayer;
		hitPlayer = Instantiate(projectilePrefab, transform.position, transform.rotation) as Rigidbody;
		hitPlayer.velocity = transform.TransformDirection(Vector3.forward * 100);
		//            Physics.IgnoreCollision ( projectilePrefab.collider, transform.root.collider );

	}

	for(var i =0; i < Input.touchCount; ++i)
	{
		if(Input.GetTouch(i).phase == TouchPhase.Began )
		{
			Rigidbody clone;
			clone = Instantiate(projectilePrefab, transform.position, transform.rotation) as Rigidbody;
			clone.velocity = transform.TransformDirection(Vector3.forward * 200);
			//            Physics.IgnoreCollision ( projectilePrefab.collider, transform.root.collider );

		}
	}

In line 30 of your script try the easy way

clone = Instantiate(projectilePrefab);

What does this do?

it just instantiates the object with the rotation and position of the current object
