- fixed problem in remoting (not able to get version info without providing server_id argument), fixes #4801

and server_get_functions

Fixed #4057 Remote API: some API calls are not working because the form definition files are missing

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)

Conflicts:
