	No reason why not to allow more then one address: `transfer to 127.0.0.1 10.240.20.1`. Fix startup as well, as it turned out to be broken...

file
file enables serving zone data from a RFC-1035 styled file.
The file middleware is used for "old-style" DNS server. It serves from a preloaded file that exists on disk.
Syntax
file dbfile [zones...]
- dbfilethe database file to read and parse.
- zoneszones it should be authoritative for. If empty the zones from the configuration block are used.
If you want to round robin A and AAAA responses look at the loadbalance middleware.
TSIG key configuration is TODO; directive format for transfer will probably be extended with
TSIG key information, something like transfer out [address...] key [name] [base64]
file dbfile [zones... ] {
    transfer from [address...]
    transfer to [address...]
}
- transferenables zone transfers. It may be specified multiples times. To or from signals the direction. Addresses must be denoted in CIDR notation (127.0.0.1/32 etc.) or just as plain address. The special wildcard "*" means: the entire internet (only valid for 'transfer to').
Examples
Load the miek.nl zone from miek.nl.signed and allow transfers to the internet.
file miek.nl.signed miek.nl {
    transfer to *
}
