Add support for read-only journals.

This change only works for calendars at the moment, because we don't have shared
address books anyway.
This is currently only implemented in the client, and only as a read-only attribute,
you can't make a journal read-only yet. This requires server support that is not yet
there, but it's better to be ready for this sooner rather than later.
