Make scroll wheel behavior consistent with IJ1

Using the mouse scroll wheel on an open image display performs different actions in IJ1 than it does in IJ2. (And in IJ2, the behavior depends on which tool is selected.) For consistency, the scroll wheel logic should be updated to behave the same in IJ2 as it does in IJ1:

  • Stepping through C, if multiple channels.
  • Stepping through Z when control held, if multiple focal planes.
  • Stepping through T when alt held, if multiple time points.
  • For single channel data, panning the display up and down when zoomed in.

The current behavior of zooming the image in and out is probably more intuitive for new users, so eventually we can make it an option, depending on if "legacy display mode" or similar is set.
