Subject: Add a new "NativeWindow" class to the library. This is a pure Qt
 container class for setting/announcing changes to native windows on the
 system. This allows the WM class (XCB/Wayland-specific) to simply adjust each
 window object as needed, and the interface (pure Qt) will automatically
 adjust as needed. NOTE: Still need to adjust the LXCBEventFilter to use this
 new class, but the root window and rootsubwindow classes are all setup to use
 it.
