Add auto-detect toggle switch
Currently if a user changes the DPI, there is no way to reset it back to the auto-detected value from Xserver (which we store as 0 in gsettings). Adding this toggle solves that issue. I also removed a deprecated [GtkHandleBox](https://developer.gnome.org/gtk3/stable/GtkHandleBox.html) and all its associated code.
