update-manager should have a view that shows the changelogs together for all changes that that will be applied

[Steve Langasek]

Currently if a user wants to see the details in update-manager about the updates that are to be applied, they have to click on each individual package in the list. This is tedious and not scalable. Particularly for folks tracking the devel series and doing daily testing, it would be useful to have a way to get a view of all the changes at once.

<https://wiki.ubuntu.com/SoftwareUpdates#expanded>: "The contents of the “Technical description” pane should depend on how many updates are selected in the list above: ... If more than one, the name and version (but not the description) of each selected package, each followed by a spinner which is replaced by the changelog for the update once it loads (or “The list of changes is not available.” if it fails to load), and each separated by a horizontal rule."
