Add permission 'collective.depositbox: View Data'.

Allow access to 'get_all_confirmed' data when the user has this
permission.

We do not grant the permission explicitly, so by default only a
Manager has it.
Add simple 'deposit-box-data' view to see confirmed data.

You may want to override this in your own code with some view that
presents it in a nicer way because it knows what kind of values are
stored.
Add deposit-box-data.csv download view.
utf-8 character set seems fine
Add locales, with Dutch translations.
