Title: Add friendly urls

This adds friendly urls (using friendly_id gem) :
Sheets' url will contain their title instead of their id, which will be more useful and pleasant for people.
To affect the sheets already registered in the database, after running migration,
one should type this in the rails console :
> Sheet.find_each(&:save)
