GUI: Rethink detector image context menu (right-click)
The new context menu uses a right click, which is also bound to zooming out to the next zoom frame in the stack. It is very easy to accidentally reset the image by accident. Moreover, if you clear the image by accident, there is no way to get the verious plots back. In fact, in most instance it is not generally obvious how to repopulate the image. I thinkn that for most users, resetting the image is something they will rarely if never want to do so I'm not sure it makes sense here.
I am tempted to remove this context menu because all three controls are not dependent on the position of the cursor. Therefore, I think they should be moved to the menu.
