* Add support for an array of values in 'type'.
* Introduce `type__in` parameter. This duplicates 'type' but is added for better consistency with other query classes.
* Introduce `type__not_in`.

Among other things, these changes will make it easier for plugin authors to
manage the appearance of custom comment types in various WP interfaces.

Props dancameron, mordauk.
