* Remove experimental pinning feature again and instead allow using a
normal window
* Pinning made it inconvenient to close the (frameless) window again
* Pinning required hiding/showing the window which didn't look very
nice (and setting flags directly via `QWindow` didn't work as well)
* As normal application/window positioning issues on Wayland are less
problematic (and those aren't going to be fixed any time soon, if at all)
Otherwise it is not really possible to go back to the start page. Besides,
triggering the setup detection again explicitly might make it more obvious
what's going on.
* Allow using icons from freedesktop.org icon theme for most ForkAwesome
icons if available
* Let's not use it for the nested list of details in the models for now
* See https://github.com/Martchus/syncthingtray/issues/121
The default of 32 px should be fine in most cases and when the UI is scaled
it is also automatically scaled. However, if one has a tray area or Plasma
panel with extraordinarily big icons like latte-dock it might still be
required to render icons at a higher resolution. This is hard to determine
programmatically so I'm just adding a manual setting.
The external inotify tool is likely not used anymore. It makes sense to
keep the concept of supporting additional tools because it might be used
in the future again. So it seems best to give the additional launcher a
more generic name.
