Make it easier to add CNAMEs

[bigwillystyle42]

Every time I try to add a CNAME I'm told it's not valid without much indication as to why. I don't add them frequently enough to remember to put the "." at the end. The previous management software I used (smbind), would silently handle this.

It'd be nice if fmDNS would silently take care of this case as well.

That should be simple enough to add. Thanks for the suggestion!
