Support for in-memory zones for slaves

[anon]

# Zone that is not stored to disk zone "example.com" {

type slave; memory-only yes; masters { 127.0.0.1; };

};

A better sample, since I forgot wikiformatting...

zone "example.com" {
 type slave; 
 memory-only yes;
 masters { 127.0.0.1; };
};

Better version

Please use only the second version. It changes behaviour so, that you can enable memonly behaviour by leaving out the filename.
