* add wildcard parameter to allow resolving multiple name to the same IP
* first test for the reverse wildcard middleware
* update wildcard keyword test to pass code coverage
* middleware/reverse: random updates
Make the documentation somewhat shorter (and hopefully clearer in the
process). Also to be on-par with the *auto* middleware, start counting
the referenced zones from 1 (instead of 0).
Some variable cleanups and use the NextOrFailure in the ServeDNS
function.
* More TODOs
