* Adds local file:// URL support to the [validator_list_sites] stanza. The file:// URL must not contain a hostname. Allows a rippled node operator to "sideload" a new list if their node is unable to reach a validator list's web site before an old list expires. Lists loaded from a file will be validated in the same way a downloaded list is validated. * Generalize file/dir "guards" from Config test so they can be reused in other tests. * Check for error when reading validators.txt. Saves some parsing and checking of an empty string, and will give a more meaningful error. * Completes RIPD-1674.
