Explosive

This problem in **_custom_error_message.rb:45:in full_messages** too `I18n.t(:"errors.format", options.merge(:message => m))` must be changed to `I18n.t(:"errors.format", **options.merge(message: m)` It is deprecated but works

This code is confusing(readme.md): `provider :vkontakte, ENV['API_KEY'], ENV['API_SECRET']` Probably it can be better: `provider :vkontakte, ENV['VK_API_ID'], ENV['VK_API_SECRET']` I made mistake too
