reworking of failover.pl internals -- more verbose output; greater paranoia in configuration validation; support for unlimited numbers of database and backup hosts; additional commandline options; addition of test-mode only; recognition ability to promote arbitrary host from list (instead of newhost/oldhost); recognition of ability to demote multiple hosts (last two supported by configuration and planned program flow, just not yet implemented)
