Some of the counts are capped (wiki counts) and some are not (page
counts) - so we are adding a config option ('isCapped') to the
widget to make sure that capped numbers appear with the proper
i18n message ('99+' in English) and non-capped numbers appear
as-is.

Make it optional through the unpgrouppages parameter, so that
generic usage of the unreadnotificationpages API is still possible.
In the front-end, store which display title maps to what set of titles,
and pass in the full set rather than just the display title when
filtering by a page.

Add a sidebar with cross-wiki sources and pages of unread notifications.
The filter allows the user to fetch notifications from a foreign source
and specific pages if those exist.
