 App Settings Edit Form in Rails 5 using Mongoid

 * With mongoid-app_settings gem (https://github.com/marten/mongoid-app_settings)
 * Inspired on 'rails-settings' gem for ActiveRecord

 Made this gist because couldn't find any code/post to update this gem (or hashed arrays) with a view form on Rails.
 Based on the ZedTuX answer (Option 2) on this SO question
