Since this feature will likely not be available in mingw-w64-based builds of
the next release (due to missing cppwinrt) it is important to make it clear
when those options don't actually work. With this change the checkboxes are
completely disabled in case the feature is not available (instead of just
providing the information via the tooltip).
* Allow to pause all devices on metered network connections (devices will
be automatically resumed when network is no longer metered)
* Allow to stop Syncthing when it was started via the built-in launcher
on metered network connections (it will be automatically started again
when the network connection is no longer metered)
* See https://github.com/Martchus/syncthingtray/issues/231
* Remember new size after user resized the window
* Remember new position after user repositioned window and using explicit
coordinates has been configured in the appearance settings
* Do not blindly override existing auto start entry
* Warn if an auto start entry exists but points to a different executable
* Allow removing such an entry explicitly
