credits:
* basic omniauth-facebook integration https://coderwall.com/p/bsfitw
* econfig for configuration http://www.elabs.se/blog/57-handle-secret-credentials-in-ruby-on-rails

unsolved issue:
econfig doesn't actually load any other config file than config/app.yml;
temporarily I solved it by copying app_secret.yml to app.yml
User: 'trusted' and 'staff' flags
Vote: add relation to User
IsItOpen: show today's votes
IsItOpen: change the open/closed status according to the votes of trusted users. Print explanation.
