simpler zonefile editor for regular users

the first zonefile editor (#922250: DNS: generic zonefile editor) will be a "power user" editor: it may be incomprehensible for people not familiar with DNS (a *what* record?!). We may need a more simpler interface as in "point this domain to Aegir", "point my mail to gmail" and so on. We don't want to go all the wizardy way, but there should be a simpler interface...

Gandi.net and Dyndns.org are good examples of such distinctions.
