In-App updater for desktop and IFW.

[Mesrine]

Hello everyone,

I want to showcase a repo I have put together that will check for updates using the maintenancetool deployed by the Qt Installer Framework in the backround.

If have an update, it gives you the option to update using the maintenancetool in the background.

The methods allow also you to restart the app after the update.
I have tested this for Linux.
Is up to you to test it and improve it for macOS and Windows.

Any comment, contribution is highly appreciated.
