The "do not use saved position if it falls outside of primary screen"
commit removes the dependency on qml-module-qt-labs-settings module
so no need for the installer to install it.
Skip installation of qml debug stuff while we are at it.
- Try to gracefully close any running Imager instance by sending
a window message. Should close it automatically if Imager is not
actually writing something.
If Imager does not close within 2 seconds, prompt user to ask
if it should be terminated less gracefully.
- Change installer executable name (setup.exe -> image-<version>.exe).
- Prevent UAC prompt during compiling installer.
