Enable opening application post install from the settings

Currently, only way to open apps post install is to use the script in github and then find the application file path and then push the script individually into each app.

Since Patchmypc already knows the path for each installation, why not make it a trigger "Auto open after install" in the settings menu. Would make life a lot easier.

I remember Scappman had this functionality so would be great for Patchmypc to have it as well
