Just a cosmetic change. Does not affect the API data at all, or any internal data. When viewing a User, for his list of domains, if the domain is set to have "unlimited" bandwitdth, this really means the domain can use up as much bandwidth that the user account has to offer, it doesn't actually imply unlimited bandwidth, although that's how it's stored internally. The cosmetic change it to alter "unlimited" to show "shared". This only applies to domain lists in CMD_SHOW_USER.
