Terms&Conditions and UdemiTour: save it in the DB

[Enrico Piccini]

• Each time we get a new version of T&C, we ask to user to accept it
• Each time we change the front-end graphics, we can advice to user to have a guided tour

This is an additiornal API to consume on the front-end (instead of cookie).

Andre, when you complete your backend things, please assign this task to me :)
