I added this button because I found that I would often need to open both images simultaneously in an external viewer to get a closer look at the difference in details. This button saves time if you know you want to open both images, versus clicking on one image in AnitDupl, then minimizing the external viewer application that pops up, then switching back to AntiDupl to open the other image.
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.
Consolidated & relocated redundant code in ImagePreviewContextMenu & PictureBoxPanel to open an image; this code is now in new class: ImageOpener.
