Keep track of accomodation & payment type after confirmation

[udebella]

Linked to #5 This part focuses on keeping track of accomodation (single-room, double-room, triple-room or no-accomodation) and payment type (Payment at checkout, cheque, transfer) after each confirmation.

@fakih Do you need to keep track of confirmation dates? Do you set that manually or the system should handle that automatically for you when you confirm a candidate?
