add subdomains to domain alias

[platzwart]

why is it not possible to add a subdomain to a domain alias? a lot of customers would like to manage all their domains with one account. so it should be possible to add subdomains to all domains of an account...

it's already good enough to be able to mount a domain alias on an existing mount point... so don't expect that other feature for 1.0.0
