Create a contact for the domain owner

There are advantages to storing the information on the civicrm/admin/domain in a contact record. One benefit is that this contact can be made the owner of financial accounts in CiviAccount. The attached patch to be provided by Pradeep standardizes how the information about the organization that is running CiviCRM is stored, so that it is a contact like other contacts. Note that the system generated mail settings are not yet included as information for the domain contact, though the contact email at the bottom of this admin page is.
