Added new button next to duplicate image results (above the Open Both…

… Folders button), with tooltip text "Open both images". Clicking this will open both of the displayed images simultaneously in the associated external image viewing application;

Added new PNG image of two images;
Adjusted column/row spacing of the button strip in both horizontal and vertical views, to keep the Go To Next/Previous Result arrow buttons centered, after the addition of the Open Both Folders & Open Both Images buttons.
