* Refactor shouldUpdateScroll passing

So far, shouldUpdateScroll has been manually passed down from the very top of
the React component hierarchy even though it is a static function common to
all ScrollContainer instances, so replaced that with a custom class extending
ScrollContainer.

From the start, swiping columns was highly unreliable because the logic
could change `ReactSwipeableViews`'s `animateTransitions` property
mid-swipe.

PR #11200 partially fixed this, but at the unintended cost of disabling the
swipe animation altogether.

This PR changes the logic behind `shouldAnimate` to only disable the swiping
animation at the end of a column change not initiated by `ReactSwipeableViews`.

* Fix scheduler unpublishing announcements before they are due

* Fix filter params not being passed to announcements filter

* Add follow_request notification type

The notification type already existed in the backend but was never pushed
to the front-end. This also means translation strings were also available
for the backend, from the notification mailer.

Unlike other notification types, these are off by default, to match what
I remember of Gargron's view on the topic: that follow requests should not
clutter notifications and should instead be reviewed at the user's own
leisure in the dedicated column.

Since follow requests have their own column, I've deemed it unnecessary to
add a specific tab for them in the notification quick filter.

* Show follow request link in single-column if there are pending requests, even if account isn't locked

* Push follow requests from notifications to the follow_requests list

* Offer to accept or reject follow request from the notification

* Redesign follow request notification
