From 9df541f95f12d2fad5c9911008882b7ff35a9514 Mon Sep 17 00:00:00 2001

Subject: Implement package difference filtering

This is done as client-side JS which makes the page nice and fast. Minor
versions can be excluded, as can packages in [multilib]. In addition,
architecture filtering is in place so you can limit the subset of shown
packages to those in any, both, one or the other.
