Subject: [PATCH] Add configuration class and modify lookup to use this
 configuration

To configure the module, you can use :
ProjectHoneypot.configure do
  @api_key = 'API_KEY'
end
To access, the variable, use :
ProjectHoneypot.api_key

The lookup method has been modified to be backward compatible
and use the defined api_key if available.
