* 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
When the calling code does not return to the event loop (like the CLI test)
we need to run the event loop internally to make sure `bufferOutput()` is
called as of ecd730fd49.
* Add page to apply settings
* Add page to show final result
* Fix updating systemd checkbox (`isVisible()` did not work because when
the function is running the whole page is not visible)
* Enable systemd integration by default if either the user service or the
system service are running
* Fix typo
At least when using Qt 6 I could reproduce crashes very often when invoking
`syncthing -version` as part of the wizard's setup detection (inside
a `QIODevice::readAll()` call).
I suppose the problem is that the callback `bufferOutput()` is already
invoked on another thread and emitting the next `readyRead()` signal while
Qt is still handling the previous `readData()` call. Continuing reading
from the pipe only after `readData()` returns should fix it. At least it
does not crash anymore with that change in the wizard's setup detection.
Set the ABI version (used in so/DLL name) to 2 and increment it on an ABI
break (but only once within one release cycle). This way we don't need to
increment it on every patch release but also don't need to make a new major
release on every ABI break.
Keep the API version as is (using the semantic versioning format).
* Remove `0 &&` in condition for making `QPalette` from Plasma theme
* Set `WindowText`/`Window` of `QPalette` in legacy case so
`isPaletteDark()` works
* Set the icon manager's palette from the beginning (and not only if the
Plasma theme changes)
