Add a new alias type, urltable, which downloads a file of IP/CIDR addresses and loads them into a pf persist table instead of importing the addresses directly into a traditional alias. This allows for using huge tables of addresses that would otherwise break the GUI and/or fail to load into pf. Part of ticket #512
