Subject: [PATCH 1/5] extensions: Resurrect systemMonitor extension
The extension was removed upstream because:
- it hooks into the message tray that was removed
- it was known to have performance issues
- there are plenty of alternatives
Those aren't good enough reasons for dropping it downstream
as well though, so we need to bring it back ...
This reverts commit c9a6421f362cd156cf731289eadc11f44f6970ac.

Subject: [PATCH 3/5] systemMonitor: Move indicators to calendar
The message tray joined the invisible choir, so we have to find
a new home for the extension UI. The message list in the calendar
drop-down looks like the best option, given that it replaced the
old tray (and also took over the old keyboard shortcut to bring
it up quickly).

Subject: [PATCH 4/5] systemMonitor: Handle clicks on section title
While on 3.24.x only the event section still has a clickable title,
it's a generic message list feature in previous versions. It's easy
enough to support with a small subclass, so use that instead of
the generic baseclass.
