SliceViewer: Link two (or more) windows together

[mantid-builder]

This issue was originally TRAC 4242

Original Reporter: @jzikovsky

Come up with some sort of GUI to allow two plots to be linked together. You might want to link:

• The X/Y panning and zoom on the plot
• The dimension settings (e.g. slider positions) at the top
• The color map, range and log setting
• Perhaps the line drawn in one plot to the other?

The two SliceViewers might be from the same or two different workspaces.

GUI: Maybe have a small dialog with some checkboxes and some link to the two windows?
