Update lumina-calculator a bit:

1) Re-arrange the buttons a tiny bit to match what a numpad looks like (based on user feedback)
2) To fill the empty spot in the corner, add a "percent" button and add handling for that within the solver.
3) Adjust all the button properties so that the window can be resized down to a much smaller footprint as desired.
