Notifications

[andersoncardoso]

• add notifications backend
• show notifications (with counter badge + modal for displaying them)
• mark as read when user opens the modal
• real time using Faye

OBS: @LuizArmesto vc precisa atualizar seu application.yml para o faye rodar, deve ter o FAYE_TOKEN (qquer string), ele precisa estar na seção default do yaml (como no sample).
