//	Access:  public
//
//	Arguments:

//	Description:	Refresh an item in the ListView.  Reset all its attributes to the appropriate

//
//						This function overrides the real of_RefreshItem to allow the DataStore row
//						to be optional.

//						have changed, this function will not work.  It will no longer be

//						of_RefreshItem(al_Item, ai_Row)
