0.9.x -> 1.0.0, incompatible changes to db schema were made

`whitelist` table's schema was changed, the plugin will run automatic
migration if old db structure is detected. This means that plugin
will still work just fine, BUT anyone who used the old db schema in
their projects will have to change it to keep compatibility.
