Ruby on Rails deployment & Argentinian marketplace adaptation using MercadoPago api

Project written on Ruby 2 on Rails 4.2, needs to be deployed. Frontend built with Jquery 1.2. The web is able to register, login and recovery password for users. Allow each user to create their own 'microsite', and inside of each microsite the user can create and manage their 'microsite discount coupons' and 'microsite categories'.

All is working, except the payment platform, which is going to be re-written using this documentation: https://www.mercadopago.com.ar/developers/en/guides/online-payments/marketplace/checkout-pro/introduction
