Fixed #2738 Installing package from APS to root of subdomain fails when/if. Thanks to @gardan for the patch.

Posibility to change main-domain of aps-instance over remote (in interface maindomain is always the websites domain but over remote it's now possible to set an alias oder subdomain, that will be used in instance-settings. Important if e.g. wordpress-installation should run unter an aliasdomain instead of the websites domain)
