Some new features, my 20 cents.

From what I understand, the requests were being made ​​every 5 minutes and not every 5 seconds ([Check this](http://cronchecker.net/check?utf8=%E2%9C%93&statement=*%2F5+*+*+*+*+*&button=)). I changed to 1 minute.

I changed to use the heroku environment variables. Thus it is not necessary to change the code to use the bot. 

Added support for multiple languages​​, the default is English.
