Added two new fields to the keys table: 1) is_private_key and 2) ip_addresses. These two  fields work together. If the key is private a list of IP addresses can be associated with the API key, If the API key is private and no valid address if found, the request is rejected. IP addresses need to be separated by a line break n. This is an alternative to the ip-whitelist, but it is tight to the API key.
added options to force ssl and to specify api key table data
Updated comment on rest_key_column name
IP addresses are no longer separated by a line brake '\n' rather all ip addresses are coma separated.
