Revise default gateway handling for speed

Move gateway interface friendly name functionality to gwlb.inc

Revise return_gateways_array() to include the tier name in hte returned array. This avoids the need to call the function for every gateway in the array and makes life easier for system_gateways.php, which no longer needs to call multiple functions to get the display information.
