options for isURL method

require_protocol - if set as true isURL will return false if protocol is not present in the URL
require_valid_protocol - isURL will check if the URL's protocol is present in the protocols option
protocols - valid protocols can be modified with this option
require_host - if set as false isURL will not check if host is present in the URL
require_port - if set as true isURL will check if port is present in the URL
allow_protocol_relative_urls - if set as true protocol relative URLs will be allowed
validate_length - if set as false isURL will skip string length validation (IE maximum is 2083)
