Allow paging instead of infinite scroll in feeds

[oscarnylander]

Infinite scroll can unintentionally promote unhealthy consumption patterns. Paging can help create natural 'exit points', which in turn improves user agency over their consumption patterns.

I agree with this fully. If anyone wants to work on that, I'd be glad to merge it.

This would also be a good workaround for #1003
