Browse Source 
* plugin/hosts provide more configuration flexibility

This patch adds few features to the host plugin
 * no-reverse (both as first argument on the plugin line and inline)
   disable the automatic generation of reserve entries for hosts
 * ttl <duration> (inline only atm)
   allows to change the default ttl (default 5 minutes)
 * reload <duration> (inline only atm)
   allows to change the reloading interval (default 5s)

* plugin/hosts remove superfluous parameters to parse
