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.
