Not sure: Bug, feature, or other, but...
When adding contacts/companies through Admin/Import
Companies/Contacts: If contact has no company name,
contact is not automatically put in "Self" company; is
instead skipped, it seems.
And, if "Self" is added as company name in the data to
be imported, the addresses are all called "Self", where
it would be better to make the address_name be the name
of the contact. We now have hundreds of addresses named
"Self" for the company "Self."
