--the secondary configuration window can be shown
either inline or at its own window. In order to
be shown at its own window, that window must not
overlap with the main window. The new implementation
validates this at all cases.
--the wayland interface couldnt orchestrate correctly
with the corona and the application exit. The whole
architecture changed and the window manager now is
provided by corona and corona is also responsible to
keep only one instance of it and close on exit.
