QtGui.QDesktopServices.storageLocation(QtGui.QDesktopServices.HomeLocation)
and os.path.expanduser('~') will return path to the user's home
directory ("C:\Users\<user_name>") while the
better/more_common/proper/recommended/whatever place for configuration
files is somewhere under either "C:\Users\<user_name>\AppData\Local" or
"C:\Users\<user_name>\AppData\Roaming". It's somewhat like storing
settings in "~/.<app_name>" instead of "~/.config/<app_name>" on *nix.
