Tweak things to center the windowmarlin_12.90.0marlin/12.90.0lamprey_11.92.0lamprey_11.91.0lamprey/11.92.0lamprey/11.91.012.90.011.92.011.91.0

Add a onCompleted hook in Main.qml to set it's x and y coordinates to
center the window, and rework instantiation of the qml in main.cpp so
that the resulting x and y values can be queried and used in a call to
set_window_props to actually position the window.
