 #    javascript strings as 'strings'.  
 #    The assumptions are:  
 #       There has been no effort to escape ' with \'  
 #       Any \'s in the string are intended to be there as part of the URL  
 #        and must also be escaped.  
 # Parameters:  
 #     input     - The string to escape.  
 # Returns:  
 #     The escaped string (' replaced by \' and \ replaced by \\).
