Previously, if the user accidentally right-clicked, we would move on
to the next line, and there would be no way to go back to the previous
line. This would mess up their hand-picking.
Now, the "Back" button is enabled, even when the current line has no
points, and clicking "Back" when the current line has no points results
in going back a line instead.
This PR also adds a couple of extra fixes where Laue spots were not
always being drawn correctly on the canvas while hand-picking
(they were not properly updated when the back button was pressed,
and they were not drawn on the detector after the first one).
